Synthetic Diamonds and Recycled Gold

What materials are used in making ODACE jewelry?

At ODACE we choose to make our jewelry exclusively from synthetic diamonds created in the laboratory and 18K recycled gold. In this way we guarantee the traceability of our materials and we participate in building a more sustainable and ethical future.

Why use 18K gold?

Pure gold (24K) is too soft to be used in the manufacture of jewelry. It would deform too quickly at the slightest shock or false movement. It is therefore appropriate to mix pure gold with an alloy of other metals. 18K gold is composed of 75% pure gold, and 25% of an alloy of silver and copper (and sometimes palladium) in varying quantities depending on the color of the gold desired (yellow gold, gold pink or white gold).

18K gold is the most precious of alloys, ideally used in jewelry because it has many advantages: it makes gold more solid and resistant, without ever compromising its stainless and non-allergenic properties. 18K gold jewelry is worn for a lifetime, resists corrosion and never oxidizes, even in contact with water. They are marked with an eagle's head punch to differentiate them from other alloys.

Why use recycled gold?

We started from an observation: according to the World Gold Council, humanity has already extracted nearly 80% of the gold present underground. Furthermore, gold mining causes irreparable damage to the planet and populations. The use of highly toxic cyanide and mercury contaminates soil and groundwater forever. Gold mining requires colossal quantities of water.

On an ethical level, working conditions in mines, exposure to toxic fumes, smuggling, are all alarming and disturbing flaws but unfortunately very real. But because we are great optimists and we prefer to see the glass half full rather than half empty, we are happy about one thing: gold is indestructible and has the capacity to be recycled infinitely.

At ODACE, we therefore choose to recycle rather than extract. Our COC certified recycled gold comes from old jewelry and electronic components. Thus, we give new life to this unearthed, melted and transformed gold, through our 18-carat gold jewelry that is as desirable as it is ethical and responsible.

Why only use synthetic diamonds and not mine diamonds?

Mine diamond extraction does not respect ODACE values. The synthetic diamond is an innovative solution to the abuses of the diamond industry: depletion of the earth's resources, overexploitation of human beings, pollution, conflict diamonds and smuggling.

At ODACE, we work at our level for a more ethical and responsible future. This synthetic diamond is proof that more ethical and responsible jewelry can be built thanks to human and technological progress, while preserving our ancestral artisanal know-how. This fascinating evolution today offers jewelry a new lease of life and allows it to be part of the era of time.

Are lab-grown diamonds real diamonds?

Synthetic diamond has exactly the same physical, chemical and visual properties as mined diamond. A gemologist, with the naked eye, with a magnifying glass or even with a x10 microscope, cannot differentiate it. It's a diamond.

Their only difference: their origin. One comes from mines, the other is created in the laboratory by man. The fruit of science and technological innovation, the synthetic diamond is today the only completely traceable diamond designed with respect for people and the planet.

How is synthetic diamond created in the laboratory?

Thanks to technological progress, it is possible today to afford a diamond while leaving our earth intact. Indeed, by reproducing in the laboratory the terrestrial conditions conducive to the formation of a diamond; pure carbon put under high pressure and high temperature; we are capable of creating real diamonds, identical to those extracted from mines, but with less human and environmental impact.

Which laboratories do ODACE diamonds come from?

At ODACE, we select our partner laboratories according to precise criteria: excellence, environmental sustainability and fair labor practices.

Although the laboratories are state-of-the-art, growing a diamond remains extremely difficult. Production capacities around the world are limited. This is why we are diversifying our partnerships and turning to several laboratories located in the United States and Asia.

The sourcing of our synthetic diamonds is certified carbon neutral, meaning that the energy consumed to produce our diamonds is reduced as much as possible and offset by funding carbon capture projects.

What is the quality of the diamonds that ODACE offers in its jewelry pieces?

At ODACE we only offer you the cream of the crop, the best possible quality for diamonds. Our criteria are strict, we only select diamonds of D, E or F color and clarity greater than or equal to VS.

To find out more about diamond quality criteria, click on “ Synthetic diamond ".

Do ODACE synthetic diamonds come with a certificate?

All our diamonds over 0.5 carat are certified by the most famous gemmological institutes: IGI, GIA or HRD. Our jewelry pieces featuring a diamond of more than 0.5 carat are accompanied by an official certificate. It is a sort of diamond identity card attesting to its uniqueness, weight, color, size and purity.

Do you offer colored stones?

To date we work exclusively with diamonds. At the moment, only diamond can be created identically in the laboratory – with exactly the same physical, chemical and visual properties. Given their more complex chemical formula, it is still particularly difficult to create identically colored stones in the laboratory. If technology evolves and allows us to obtain colored stones physically, chemically and visually identical to those extracted from the earth, we would be happy to offer them to you. For the moment we are focusing on the diamond, this fascinating stone with a thousand rainbow lights which continues to make us dream.
