Terms and conditions

Choosing an engagement ring is not a simple purchase. It's writing the first chapter of a shared story, etching into the material a feeling that transcends time. Every detail counts: the metal that embraces the stone, the light that shines from the diamond, the shape that graces the hand of the one who will wear it.

At ODACE, we believe that an engagement ring should reflect your love: sincere, lasting, and radiant. That's why we've chosen to work exclusively with recycled 18-karat gold and lab-grown diamonds (also known as synthetic or lab-grown diamonds) . These are genuine diamonds, created through science, identical in every way to diamonds mined from the earth, but without any ethical or environmental compromises.

This guide is here to accompany you on this quest: to understand, to feel, to choose, and finally to offer a piece of jewelry that will become the setting for your most precious memories.

Step 1: Understanding the symbolism

An engagement ring is not just a piece of jewelry. It is a promise, a future legacy, a visible sign of an invisible commitment. Since antiquity, the ring has symbolized eternal union: an endless circle, reflecting a love that never ends.

But beyond the form, there is meaning. Each ring tells an intimate story, that of an encounter, a unique bond, a “yes” that is being prepared.

Today, this symbol takes on a new dimension: it also expresses your values. Choosing an engagement ring with a lab-grown diamond is a way of affirming a modern, conscious love that unites tradition and innovation. At ODACE, this means combining the timeless purity of the diamond with respect for the planet and a celebration of French jewelry craftsmanship.

Because an engagement ring isn't just what you see on your ring finger. It's what you choose to say to the world: "This is our love, and this is what we believe in."

Step 2 — Find the style that suits her

Every love story is unique, like a fingerprint. Some are marked by simplicity and obviousness, others by boldness or the poetry of detail. The engagement ring, through its style, becomes a mirror of this unique personality. Each setting tells a different story: that of timeless elegance, understated refinement, confident brilliance, or daring creativity.

The Simple Solitaire

The solitaire embodies the simplicity of your love, free from artifice or distractions. It highlights the depth of the central diamond and the strength of your feelings. This engagement ring captivates with its purity and timeless elegance.

The woman who wears a simple solitaire embraces subtle elegance and unadorned beauty. She knows that sometimes, less is truly more. She chooses the grace of a single diamond over ostentatious embellishments.

She prefers timeless essence to fleeting trends. She sees beyond fashions and envisions her ring as an heirloom that will be passed down through generations.

A solitaire is the promise of pure love and eternal elegance.

The Paved Solitaire

The pavé solitaire is a subtle marriage of tradition and modernity. Around the central diamond, fine rows of diamonds sparkle along the ring, like a discreet constellation that enhances the light of the main stone.

The woman who wears the pavé solitaire appreciates the delicacy of detail. She values ​​jewelry that reveals its brilliance in small touches, without ever falling into ostentation.

She is sensitive to contemporary refinement: an alliance between classic elegance and a modern touch, which makes this model a safe and unique choice.

She has a taste for light and for discreet grace, and finds in paving a way to pay homage to the richness of shared moments.

The pavé solitaire is a ring that shines like a secret: intimate, refined and subtle.

The Solitary One surrounded (halo)

In a halo, the central diamond is enhanced by a crown of smaller diamonds that surround it, intensifying its brilliance and giving it a special majesty.

The woman who wears solitaire jewelry loves pieces that catch the light and attract attention. She embraces her femininity, her presence, and her charisma.

She is drawn to harmonious splendor, where every detail contributes to an overall beauty. For her, the halo symbolizes constant support and a strong union.

She is drawn to grand gestures and luminous symbols. Her ring is as much an adornment as a promise.

The solitary figure surrounded by stars embodies shared light: a radiant diamond, supported by a constellation of stars.

The Solitaire shouldered

The solitaire with side stones combines tradition and balance. On either side of the central diamond, two stones support and structure the setting, creating a subtle interplay of volumes and reflections.

The wife of the solitary man with shoulders has a deep respect for tradition, but likes to add a contemporary touch that sets her apart.

She seeks the perfect balance: between sobriety and brilliance, between stability and movement.

She is sensitive to the symbolism of the two stones that accompany the main diamond, as an echo of the strength of a united couple.

The solitaire with shoulders reflects the idea of ​​a balanced, solid and sustained love over time.

The creative engagement ring

The creative ring breaks free from conventions. It plays with volumes, curves, colored stones or unexpected compositions to offer a unique piece of jewelry, reflecting the story it tells.

The woman who wears a creative ring isn't afraid to stand out. She sees her ring as a canvas on which to express her identity, her freedom, and her boldness.

She follows her own path, often a pioneer in her choices, and finds in a unique design the reflection of her character.

She is drawn to originality and creations that break the mold. For her, an engagement ring should be a living work of art.

The creative ring is a statement: that of a unique love, unlike any other.

💎 ODACE Tip : When in doubt... Always prioritize simplicity and timeless elegance over originality at all costs. If you're overwhelmed by the choices, opt for a simple solitaire, a pavé solitaire, or a solitaire with a border: reliable, refined, and universal choices that almost always win hearts.

Step 3: Define your budget accurately

As we know, an engagement ring is a precious piece of jewelry, which necessarily requires a well-considered budget.

But be careful: focusing solely on price is a mistake. The most important thing is to find a ring that truly reflects her personality, rather than aiming for prestige that won't last.

Conversely, opting for a low-end option would be taking an unnecessary risk: that of disappointing or giving the impression that your gesture does not live up to your feelings.

Pride and long-term investment

Your fiancée will wear her ring every day for years to come. It's therefore essential to choose a quality and design that will stand the test of time. In 10, 20, or 40 years, you'll be proud to see it still shining on her finger.

Everyday comfort

A piece of jewelry should be beautiful, but also practical for everyday wear. A well-designed ring is one you love to put on every morning, without ever hesitating.

The right balance

In the United States, it's customary to spend three months' salary on an engagement ring. In Europe, things are much more flexible. One to two months' salary is often considered a good guideline, but it's by no means a requirement. What matters is offering a ring that is truly stunning, while remaining within your financial means and financial goals.

Emotion before the prize

An engagement ring is more than just its price. It carries your story, your promises, and your memories. In a few years, the price will be forgotten, but the emotion will remain.

ODACE support

Defining your budget isn't always easy. At ODACE, we take the time to discuss your needs with you, in complete transparency, to find the ring that embodies your dreams, balance, and peace of mind. Whatever the amount you invest, our commitment and passion remain the same: to offer you a piece of jewelry that shines today, tomorrow, and for a lifetime.

Step 4: Choosing the metal

The metal is not merely the setting for the diamond; it is the backdrop that reveals its brilliance and expresses a personality. White gold, yellow gold, rose gold, or platinum: each color has its own unique character.
identity and its charm.

To guide your choice, start by observing the jewelry your partner usually wears. Does she like gold, silver, or rose gold tones? Her daily life and style are often the best indicators.

At ODACE, our customers predominantly choose white gold (50%), followed by yellow gold (30%), rose gold (10%) and platinum (10%).

18-carat white gold

White gold is the most popular metal for engagement rings. It represents 50% of ODACE's collections. Its light and luminous hue creates an elegant contrast that enhances the brilliance of the diamond.

Why choose it? Because it gives an impression of increased brilliance and highlights the purity of the stones.

For whom? For those who love discreet modernity, refined simplicity and timeless brilliance.

💎 White gold embodies elegant modernity: it lets all the light shine through to the diamond, like a clear sky that magnifies the stars.

18-carat yellow gold

Classic and radiant, yellow gold is the metal of traditions and precious heritage. Its golden color warms the diamond and evokes a timeless promise.

Why choose it? Because it flatters most skin tones and never goes out of style.

For whom? For lovers of authenticity, heritage and the eternal warmth of symbols.

💎 Yellow gold is the light of the eternal sun: warm, timeless, reassuring.

18-carat rose gold

While less common in Europe, rose gold is immensely popular in the United States, where it has become a favorite choice for engagement rings. Its soft, powdery hue lends a romantic and contemporary touch to the ring, setting it apart from more traditional golds.

Why choose it? Because it embodies a tender, modern and unique elegance.

Who is it for? For romantic and sensitive personalities who want a touch of originality without falling into extravagance.

💎 Rose gold is modern poetry: a universal sweetness that colors love with a subtle nuance and is seducing more and more couples around the world.

Platinum

A rare and prestigious metal, platinum has always been synonymous with excellence. Its natural brilliance never fades, and its exceptional density offers unparalleled durability. Historically, platinum jewelry was more expensive because it was more time-consuming and complex to craft. But today, with the soaring price of gold, platinum is making a comeback: it has become a desirable alternative, almost as expensive as white gold jewelry.

Why choose it? Because it stands the test of time without ever losing its luster.

Who is it for? For those who want an exceptional metal… but also for those who do not wish to have to maintain their jewelry over time.

💎 Platinum is the embodiment of the exceptional… and more accessible than we think today.

What quality of gold should I choose?

Not all gold is created equal. In jewelry, the gold standard remains 18-karat gold (750/1000): it contains 75% pure gold, alloyed with 25% complementary metals (silver, palladium, copper) which give it hardness and color. This balance is what gives it its brilliance, durability, and everyday comfort. It is also the only alloy recognized by fine jewelry.

18k gold is identifiable by an official hallmark in the shape of an eagle's head , a guarantee of quality and authenticity.

Platinum , on the other hand, is marked with a dog's head hallmark, another symbol of trust in French tradition.

Conversely, 14k gold (58.5% gold) or 9k gold (37.5% gold) contain significantly less pure gold. Duller and more fragile, they are more likely to lose their luster quickly, oxidize, or even break at the setting. A 14k or 9k engagement ring may eventually loosen its diamond over time.

💎 ODACE Tip : For a piece of jewelry as precious and symbolic as an engagement ring, don't compromise. 18k gold or platinum are the only metals capable of lasting a lifetime without losing their beauty or value.

Why avoid money?

Silver is often appealing because of its bright white color and attractive price. But behind this apparent beauty lies a very different reality: this metal is too soft and unstable for an engagement ring.

Over time, it oxidizes (it darkens upon contact with air and humidity), it tarnishes (it loses its natural luster), it deforms easily (its malleability weakens the setting), and, even more seriously, it can eventually release the stones it is meant to hold. Imagine the worry of seeing a precious diamond come loose simply because the metal wasn't strong enough.

Even if your partner enjoys wearing silver jewelry every day, it's important to distinguish between costume or casual jewelry and engagement jewelry. An engagement ring is a piece of jewelry for life: it must withstand years of daily wear, repeated gestures, and intense moments.

💎 ODACE Tip: For lasting white brilliance and optimal security, opt for 18-karat white gold or platinum. These precious metals retain their beauty and strength for decades.

✨ An engagement ring is not a piece of jewelry that can be changed: it's an eternal promise. Money, on the other hand, is not meant to last that eternity.

Step 5: Choosing your center stone

The reign of the diamond

For centuries, the diamond has reigned supreme on the engagement ring. Far more than a precious stone, it has become a universal symbol of eternal love.

Why do so many couples choose diamonds to seal their vows? Because they embody everything one expects from a commitment:

Absolute strength : it is the hardest stone in existence (10/10 on the Mohs scale). Like enduring love, the diamond withstands the test of time without fail.

Unparalleled brilliance : this is the stone that reflects light the most. Every glimmer of light transforms into a shower of sparks, recalling the magic of shared memories and moments yet to come.

A rare versatility : the white diamond complements all skin tones, all metals (white, yellow, rose gold, platinum) and all styles. It transcends trends and can be worn every day with the same intensity as the first day.

💎 Choosing a diamond (natural or synthetic diamond) is choosing a symbol that, like your story, is made to last forever.

The 4Cs of diamond: understanding quality

Each diamond is unique, and to evaluate its beauty as well as its value, we refer to the 4Cs : Carat, Color, Clarity, Cut.

Carat (weight): The carat measures the weight of a diamond (1 carat = 0.20 g). But be aware: the carat alone does not determine the value . Two diamonds of the same weight can have very different qualities depending on their clarity, color, and cut.

Clarity: Every diamond has inclusions , tiny imprints left during its formation. The purer a stone is, the rarer it is. The scale ranges from FL (Flawless – without any inclusions) to I (Included – inclusions visible to the naked eye) .
At ODACE , we select only diamonds of VVS clarity or higher , guaranteeing a clear and luminous stone.

Color: A quality diamond is also defined by its degree of colorlessness. The international scale ranges from D (exceptionally colorless) to Z (yellowish or brownish tints) .
At ODACE, our diamonds are exclusively graded D or E : the pinnacle of white, for a crystalline and timeless brilliance.

Cut: The cut is undoubtedly the most crucial factor. It's what reveals the magic of light. A perfectly cut diamond (proportions, angles, polish, symmetry) reflects every ray to create a dazzling fire.
At ODACE , all our diamonds are cut in Excellent (EX/EX/EX) , the best quality available.

💎 A well-chosen diamond represents the perfect balance between these four criteria. It guarantees a brilliant, harmonious, and lasting stone.

Certification and Transparency

At ODACE, every diamond over 0.40 carats comes with a certificate issued by the IGI (International Gemological Institute) or the GIA (Gemological Institute of America) . These independent organizations are world authorities and apply the same strict criteria to lab-grown diamonds as to diamonds mined from the earth.

This document, a true identity card for the stone , certifies its characteristics according to the 4Cs (carat, color, clarity, cut). It is not a mere formality: it is the guarantee that your diamond is unique, analyzed in every aspect by experts, and recognized for its exceptional quality.

But beyond the technical aspects, this certification has emotional value: it assures you that the stone adorning your ring holds no secrets, that it is traceable from its origin, and that it embodies a conscious choice. Where mining often leaves room for uncertainty, cultured diamonds (also called synthetic or lab-grown diamonds) come with complete transparency , clearly stated in black and white.

💎 At ODACE, we believe that love deserves clarity. Certification is not just a guarantee of trust: it's tangible proof that your engagement ring carries within it the same truth as your commitment.

The shapes of the diamond: a choice of personality and perception

Each shape of your gemstone tells a different story, and influences how the stone captures light… and the perception of its size.

Round : the most classic and brilliant shape. It maximizes sparkle and remains timeless. It's the absolute benchmark for shimmer.

Oval : highly sought after today, it visually lengthens the finger and gives the impression of a larger diamond for the same weight. Its elongated shape allows for up to 10-15% more apparent surface area compared to a round diamond of the same carat weight.

Pear-shaped : elegant and original, it combines the softness of an oval with the point of a teardrop. Like the oval, it offers a volume effect greater than its actual weight, giving the impression of a more imposing stone without increasing the budget.

Cushion : with vintage charm, featuring rounded corners and deep facets that create a soft and romantic glow.

Emerald : more architectural in style, it is distinguished by its large, stepped facets. Less sparkling than a round or oval shape, it captivates with its transparency and retro elegance.

Colored synthetic diamonds

Many couples who want a colored engagement ring first think of a sapphire or emerald. But did you know that diamonds can also be colored?

In nature, colored diamonds are among the rarest and most expensive gems in the world. A one-carat green diamond, for example, can fetch over €50,000 . Blue, pink, yellow… these marvels are almost unattainable.

Thanks to lab-grown diamonds, these precious stones are finally becoming a reality for everyone. Colored synthetic diamonds (or colored lab-grown diamonds) possess the exact same properties as white diamonds : unparalleled hardness (10/10 on the Mohs scale), exceptional brilliance, and lasting sparkle. But they are now available in deep blue, soft pink, or sunny yellow, for a truly unique look.

💎 ODACE Tip : Choosing a colored diamond means offering an engagement ring that breaks the mold. An ocean blue oval, a powder pink pear, or a luminous yellow cushion tells a unique story—yours.

Step 6: Personalize your ring

At ODACE, we believe an engagement ring should be unique, like the story it embodies. Beyond the choice of style, every detail can be personalized to create a bespoke piece of jewelry, reflecting your individuality. The white diamond, a universal symbol of eternal love, remains the most timeless choice. But there are countless ways to give your ring a unique character:

Choosing your stones : opt for the timeless purity of a lab-grown white diamond, or be captivated by a colored diamond (deep blue, dusty rose, sunny yellow). These rare stones add a touch of originality without sacrificing any of the diamond's brilliance and durability.

The metal : elegant white gold, timeless yellow gold, romantic rose gold (popular in the United States), or prestigious platinum. Each metal reflects a different personality and highlights the diamond's brilliance in its own unique way.

The shape of the diamond : the round, absolute brilliance and unbeatable classic; the oval and the pear, which lengthen the hand and appear more voluminous; the cushion, with retro and romantic charm.

The engraving : a key date, your initials, a secret word. This detail, invisible to others but eternal to you, makes the ring even more intimate and personal.

Custom-made : If you dream of a design that doesn't yet exist, our Parisian artisans will bring your desires to life, from the initial sketch to the finished piece. Your ring becomes a unique creation, a reflection of your love.

💎 At ODACE, all these personalization options are possible. Because an engagement ring is not just a piece of jewelry, but a promise: that of an intimate symbol, designed to stand the test of time and be passed down from generation to generation.

Step 7: The quality of the jewelry

An engagement ring , whether set with a cultured diamond (also called a lab-grown or synthetic diamond), shouldn't just be beautiful at first glance. It should remain strong, comfortable, and brilliant for a lifetime.

The quality of a piece of jewelry rests on several essential pillars: its place of manufacture, the precision of the setting, the authenticity of the hallmarks, the certification of the stones, but also the finesse of its finishes and its durability over time.

French manufacturing, exceptional expertise

At ODACE, all our creations are made in France, in Paris, by hand , in workshops where several generations of artisan jewelers with unique know-how have succeeded one another.

Every detail (for example: the regularity of a setting, the fineness of a polish, the precision of a prong) is executed with extreme care. It is this invisible exacting standard that ensures a ring remains as beautiful 20 years from now as it was on the first day.

We could have taken the easy route by relocating our production, but we believe in the value of French heritage , which is both a guarantee of excellence and a source of meaning. This choice is also ethical: supporting local craftsmanship, preserving exceptional expertise, and reducing our environmental footprint.

Proof of this commitment, our workshops, all French, are labeled RJC (Responsible Jewellery Council) , Joaillerie de France and recognized as Entreprise du Patrimoine Vivant .

💎 ODACE tip : always ask your jeweler about the origin of the piece. The answer will tell you more about its durability than any price tag.

The strength of the setting

A diamond, however pure, is only valuable if it is perfectly set. A setting that is too loose risks the stone falling out over time. A setting that is too thick will stifle the light, depriving the diamond of its natural brilliance.

At ODACE, our artisans strive for the perfect balance : a setting that is both robust and elegant , where each prong perfectly embraces the stone. This meticulous craftsmanship, the result of decades of passed-down expertise, ensures that your diamond is not only protected but also enhanced.

Hallmarks, marks of trust

In France, every piece of precious metal jewelry is marked with official hallmarks that guarantee its quality and authenticity:

The hallmark : it indicates the precious metal content.

The eagle's head for 18-carat gold (750/1000).

The dog's head for platinum.

The maker's mark : it identifies the workshop or craftsman who made the jewelry.

In France , it is in the shape of a diamond , a true signature of French jewelry.

Abroad , it takes the oval shape , a sign that the coin was not made on French territory.

These hallmarks, sometimes tiny, are much more than symbols: they are true indicators of the jewelry's quality . Their presence is proof that your ring is authentic, precious, and crafted according to the highest standards of craftsmanship .

💎 ODACE Tip : If you want to be sure you're choosing a ring made in France, look for the diamond-shaped maker's mark. It's the discreet mark of unique artisanal expertise passed down through generations.

The exquisite finish

A quality piece of jewelry is also recognized by its finishing. The polish should be clean, mirror-like, without any visible scratches. The prong work should be regular and harmonious, fine enough to allow the stone to breathe, yet strong enough to secure it.

Each ODACE ring is polished and inspected by hand by our artisans to guarantee a perfectly smooth surface and balanced proportions. This exacting standard is what distinguishes a French jewelry ring from an industrially produced one.

The diamond certificate

When choosing a diamond, beauty is not enough: objective guarantees are also necessary. Any stone over 0.40 carats should be accompanied by a certificate of authenticity issued by an independent and internationally recognized gemological laboratory, such as the IGI (International Gemological Institute) or the GIA (Gemological Institute of America) .

This document serves as the stone's true identity card. It precisely describes its characteristics according to the famous 4Cs (carat, color, clarity, cut) and guarantees that the diamond you receive corresponds to what was advertised to you.

Whether it is extracted from the earth or grown in a laboratory , a diamond remains a diamond.

The certifying laboratories apply the same strict criteria and issue the same certificates.

The only difference lies in the origin of the stone, not in its gemological value.

💎 At ODACE, all our cultured diamonds (also called synthetic or lab-grown diamonds) over 0.40 carats are certified by the IGI or GIA. This guarantees you a stone of impeccable quality, recognized worldwide.

Durability & maintenance

A precious jewel lives with you. Every gesture, every shared moment leaves an invisible imprint. Over time, 18-karat gold or platinum may develop a patina or slight scratches… but far from detracting from their beauty, these discreet marks bear witness to your story.

However, we know that most of our customers like to see their jewelry as brilliant as the day they were bought. The good news? With a few simple steps, it's possible to preserve the shine and purity of an engagement ring for years to come:

Avoid repeated friction with other metals or abrasive surfaces.

Clean the setting and cultured diamond regularly with warm water, a drop of dish soap and a soft brush.

Have the setting checked by a professional jeweler approximately every 5 to 10 years, to ensure that the stone remains perfectly secure.

At ODACE, we believe a ring's story doesn't end with the purchase. We support you over time with personalized advice and the option to have your jewelry checked or cleaned in our workshops. Our clients are also welcome to visit our boutique for professional cleaning—a simple step, ideal before a special event, to restore your ring's original brilliance.

Trust in reviews

It is human nature to express disappointment more readily than satisfaction. On the internet, and especially on Google, this translates into a well-known bias: negative reviews are often overrepresented, while positive experiences, although in the majority, remain unaccounted for.

This is why a truly positive online reputation is such a powerful signal. At ODACE, we are proud to see that the vast majority of our customers take the time to share enthusiastic reviews. They highlight the quality of our engagement rings adorned with lab-grown diamonds , the beauty of our lab-grown diamonds , but also the warmth of our welcome, the precision of our advice, and the attentive support we offer at every step.

These testimonials are invaluable because they reflect more than just a purchase: they tell the story of an experience, an encounter, a moment in life. They embody the ODACE promise: to offer jewelry designed to last, but also a relationship built on trust, transparency, and emotion.

Step 8: Finding the perfect ring size

The size of the ring is a crucial detail. Too large, and the ring risks spinning or even being lost. Too tight, and it becomes uncomfortable and difficult to wear every day. A well-fitting engagement ring ensures lasting comfort, harmoniously enhances the hand, and guarantees the security of this jewel, a symbol of eternity. It should fit the finger naturally, like a second skin: neither too big nor too small.

How to measure the finger

Several solutions exist to find the perfect engagement ring size :

Bring a ring already worn on the left ring finger: we measure it with a ring mandrel (the most reliable method).

Use a printable size guide (ODACE provides theirs) for a simple estimation from home.

Ask a jeweler for advice : we can estimate the size based on morphology (finesse of fingers, width of phalanges…).

Ask for the discreet help of a loved one : a friend, sister or relative can help you steal a ring for a measurement, or simply obtain the information without arousing suspicion.

💎 ODACE Tip : Nothing replaces the expertise of a jeweler. A measurement in-store guarantees a perfect fit. Our ODACE advisors will guide you through this process with the utmost discretion.

The resizing

Even with every precaution, sometimes an adjustment is necessary after the initial request. At ODACE , we offer resizing services for your engagement ring set with a lab-grown diamond. This service is entrusted to our artisans, who work invisibly to leave no trace. Your ring will then be perfectly comfortable again, as if it had always been made for that finger.

Anticipating the wearing of the wedding ring

One crucial detail: the wedding band will often be worn alongside the engagement ring. It's therefore wise to anticipate this future coexistence. The thickness of the engagement ring, the height of its setting, and the chosen size must be carefully considered to harmonize with the future wedding band. At ODACE, we advise you on the entire pair, ensuring your hand tells a seamless and balanced story.

An engagement ring is never alone: ​​a few months later, it will share its brilliance with a wedding band. Anticipating this pairing is essential to ensure the two pieces of jewelry complement each other perfectly. The thickness of the ring, the height of the setting, and the chosen size all influence how the wedding band will fit alongside it.

At ODACE, we see the engagement ring as the first piece of an inseparable duo. Our consultants will guide you in imagining together a harmony between the ring and the wedding band: an aesthetic balance that enhances the hand and tells a single, shared love story.

ODACE services

Choosing an engagement ring is a unique, sometimes daunting, step. At ODACE , we've considered every detail to make this experience as smooth and reassuring as possible. Beyond handcrafted creation, we offer comprehensive support, befitting the importance of this moment.

At ODACE, you benefit from a personal consultation in our Parisian boutique or remotely. Our advisors take the time to understand your desires, your budget and your inspirations to guide you towards the perfect ring — whether it's an iconic model or a bespoke creation.

💎 ODACE tip: an appointment is also an opportunity to try different styles and discover, in real life, the incomparable brilliance of our lab-grown diamonds.

Certified and guaranteed jewelry

Your peace of mind is essential. All our engagement rings come with an ODACE certificate of authenticity , featuring a unique number engraved inside the ring . This discreet marking is the signature of its uniqueness and authenticity.

For diamonds over 0.40 carats, we add an official certificate issued by the IGI or GIA , attesting to the 4Cs (carat, color, clarity, cut) and guaranteeing impeccable traceability.

Our creations also benefit from a free resizing and maintenance service , so that your ring retains its beauty and shine over the years.

Financing tailored to your needs

Secure delivery worldwide

Each package is sealed, insured, tracked, and delivered against signature , guaranteeing safe and secure delivery. From the moment you open the ODACE shipping box, the magic begins: a refined case that enhances the jewelry and makes this moment an unforgettable memory.

Guaranteed responsiveness and flexibility

We understand that engagement plans can sometimes be subject to tight deadlines. At ODACE, our team is highly responsive and adapts to your constraints. Whether it's a last-minute change, an early proposal, or a final adjustment, we always find a solution to ensure your ring is ready on time.

Mistakes to avoid

You're now equipped to find the perfect engagement ring. However, a few pitfalls may still stand in your way. Because we often see the same mistakes repeated, let us share the ones you should avoid so that your proposal remains a truly magical moment.

1. Offer a discounted copy of a high-end jewelry piece

It's natural to want to draw inspiration from the icons of Place Vendôme. But offering an imitation risks sending the wrong message.

An engagement ring isn't just a piece of jewelry; it tells a story. It's better to invest in a ring that has meaning, that truly reflects her, rather than a pale imitation. Your fiancée doesn't deserve "almost"; she deserves authenticity.

2. Choosing a piece of jewelry that cannot be adjusted or exchanged

The element of surprise is magical… but it always carries an element of risk. The size might not be perfect, or the style slightly different from what she imagined.

At ODACE, we ensure this moment remains a happy memory, free from worry. Resizing is complimentary , performed by our skilled artisans for perfect comfort.

And if your partner ultimately prefers a different model, we offer you the possibility of exchanging the ring for one that truly suits her .

This way, you keep the magic of surprise, with the certainty that in the end, she will wear every day a ring chosen out of love.

3. Neglecting the image of the jeweler

The scene is set: the setting is perfect, the emotion palpable… but the jewelry box you bring out is uninspiring. The brand image matters: it contributes to the magic of the moment. Choosing a generic jeweler risks tarnishing the experience. ODACE guarantees an elegant, modern, and ethical French brand, where every detail (from the jewelry box to the service) enhances the request.

4. Believing that the prestige of the House is enough

Conversely, some major brands charge more for their name than for the actual quality of the jewelry. The brand's prestige may be appealing at first glance, but once the ring is on your finger, what truly matters is the beauty of the diamond, the finesse of the setting, and the quality of the finishing. With ODACE, you're investing in what truly matters: an ethically sourced diamond of the highest quality (D color and VVS+ clarity), exceptional French craftsmanship, and a ring designed to last a lifetime.

💎 Our ODACE tip : it's better to offer an engagement ring set with the most beautiful diamonds, designed to last for generations, than to succumb to the trappings of fleeting prestige. A ring doesn't impress by its name, but by its brilliance and the love it symbolizes.

Make this moment a unique story

Choosing an engagement ring is a unique step. We doubt, we hesitate, we're afraid of choosing the wrong style, the wrong time, sometimes even the wrong answer… And yet, the truth is simple: it's not just the ring that counts, it's the story you're going to create around it.

At ODACE, we believe that a diamond, whether lab- grown or synthetic , only truly shines when it's part of a genuine love story. The real secret to a successful proposal lies not in the number of carats or the prestige of a name, but in the emotion you share.

💎 Our final tip : The story you're going to tell her. Explain the hesitations, the time spent searching, the little doubts as well as the great certainties… These confidences are all proof of your love.

And when the time is right, choose the perfect moment, let the magic happen, and give the person you love an ODACE ring, designed in France, crafted from 18-karat recycled gold and set with the finest lab-grown diamonds . A piece of jewelry designed to last, but above all, to tell an eternal story: yours.

Frequently Asked Questions about ODACE Engagement Rings

Is a lab-grown diamond a real diamond?

Yes, absolutely. A lab-grown diamond is a real diamond, identical in every way to a diamond mined from the earth. Same chemical composition, same physical properties, same dazzling brilliance. An expert gemologist, even equipped with a magnifying glass or microscope, cannot distinguish a diamond mined from the earth from a synthetic diamond.

They are both subject to the same certification criteria by international gemological laboratories (IGI, GIA). The certificates simply mention the origin (natural or laboratory), but the evaluation remains exactly the same.

The lab-grown diamond is a major innovation in modern jewelry : it allows access to the eternal beauty of diamonds, while providing total traceability and reducing the environmental impact associated with mining.

💎 At ODACE, we select only the finest synthetic diamonds (also known as lab-grown diamonds) , of excellent cut, D color, and VVS clarity. Stones that are in no way inferior to mined diamonds, quite the contrary.

Synthetic diamond, lab-grown diamond, cultured diamond or synthetic diamond: is there a difference?

No: these terms refer to exactly the same thing. In all cases, it is indeed a real diamond , created by human hands by reproducing the natural conditions of formation (extreme pressure and temperature).

All these diamonds, whether extracted from the earth or cultivated by man, are evaluated and certified by the same international organizations (IGI, GIA), according to the universal criteria of the 4Cs (carat, color, clarity, cut).

At ODACE, we talk about cultured diamonds : because beyond science, they carry a history, a vision and a promise — that of French jewelry, ethical and responsible.

Why choose a lab-grown diamond for an engagement ring?

Because it brings together everything one could expect from a diamond in the 21st century: ethics, modernity and absolute brilliance .

A lab-grown diamond is not an imitation; it is a real diamond, indistinguishable from a diamond mined from the earth, even to a diamond expert. The difference lies elsewhere: in its origin and in the values ​​it embodies.

Ethical and responsible : a lab-grown diamond requires no mining, no moving of millions of tons of earth, no labor in questionable human conditions. It's the certainty of a stone born without compromise.

Full traceability : unlike mined diamonds, which are often difficult to trace, a lab-grown diamond is tracked from its origin. We know precisely which laboratory it comes from and under what conditions it was created . This transparency is a revolution in a sector long characterized by secrecy.

Reduced environmental footprint : producing a cultured diamond consumes far fewer resources than extracting a natural diamond, whose ecological impact is colossal.

A better price-to-performance ratio : for the same budget, you can offer a larger, purer, and better-cut diamond than by opting for one mined from the earth. In other words, more beauty, more emotion, without compromise.

💎 At ODACE, we select only exceptional lab-grown diamonds : cut with excellent proportions, D color and VVS clarity. Because we believe that love deserves the most beautiful, but also the fairest.

I'm hesitating between white gold and platinum: which should I choose?

At first glance, white gold and platinum look alike: two light and luminous metals that perfectly enhance the brilliance of a diamond. But their behavior over time and their history in the workshop are different.

18-karat white gold : it needs to be rhodium-plated regularly to maintain its white shine. Over the years, it can yellow slightly, a patina that some appreciate but which requires maintenance.

Platinum : naturally white, it never changes color. Historically, platinum jewelry was more expensive not because of the raw material (which was priced close to gold), but because platinum is more difficult to work with. Artisans spend more time shaping it, which increases the cost of the finished piece.

Today, the situation has changed: the price of gold has skyrocketed so much that platinum jewelry is now almost as expensive as white gold jewelry. As a result, platinum is now a particularly attractive alternative .

💎 ODACE Tip : If you want a precious metal that stays white forever and embodies artisanal excellence, choose platinum. If you prefer a balance between tradition and durability, white gold remains an essential choice.

How can I tell if my partner prefers a diamond or another gemstone?

In 90% of cases , the diamond remains the number one choice for an engagement ring. A symbol of eternity, it is the hardest stone in the world : scratch-resistant, indestructible, and therefore naturally associated with the strength of a commitment.

Its purity and unique brilliance make it a universal, timeless gem, easy to wear every day and to pass down from generation to generation. Wearing a diamond is to affirm that the love you celebrate withstands the test of time, like the stone itself.

And for those who want a touch of originality, there are also colored synthetic diamonds (blue, pink, yellow…) which retain the same qualities of hardness and brilliance, while offering a more personal signature.

💎 ODACE Tip : When in doubt, choose a lab-grown white diamond . More than just a precious stone, it symbolizes the strength and enduring nature of your story.
