We carefully select the laboratories that we work with. Our selection criteria : excellence, environmental sustainability, and fair labor practices.
Even though laboratories are technological experts, cultivating a diamond remains difficult. The production capacities around the world are quite limited. That is why we vary our partnerships and turn towards multiple laboratories located in the United States and in Asia.
Our synthetic diamonds are carbon neutral certified, which means that the energy consumed to produce our diamonds is limited as much as possible and is offset by financing projects on carbon capture.
The term “synthetic diamond” is actually misleading. The word “synthetic” is often associated with artificial objects. Compared to moissanite, zirconium oxide, or what we commonly call “strass”, the synthetic (or lab-grown) diamond is not artificial at all. It is not a fake gem or an imitation. It is a real diamond made out of pure carbon. Not only does the term lead to confusion but, it is also scientifically incorrect. Scientifically we can not synthesize a pure element. We can only extract it or let it grow.
So why do we continue to call it a synthetic diamond in France ? The French law imposes the use of the term “synthetic diamond” or “synthetically produced diamonds”. We are committed to make the french government evolve its legislation just like other countries have already done such as the United States. These countries have banned the term “synthetic diamond” and recommend using “lab-grown diamonds”, “cultured diamond”, or “man made diamond”.
Yes, whether coming from the bowels of the earth or a high tech laboratory, each diamond is unique depending on its weight, purity, color, and size. Each diamond is evaluated and valued around 4 factors - the 4C’s :
Carat (weight) : The weight of a diamond is measured in carats. One carat is equal to one fifth of a gram. Two diamonds that have the same weight will not necessarily have the same value since this will depend on the three other factors : clarity, color, and the cut.
Clarity (purity) Each diamond has inclusions, little inclusions that are unique. For the most part the impurities are diamond crystals or other elements stuck in the gem during the forming process. If the diamond has very little impurities, it will be very precious and rare. The purity level is defined on a scale from “FL” (flawless) to “I”(Included). All of the diamonds that we use have a clarity superior or equal to VS (very slightly included).
Color: Not all diamonds are white (colorless) but, the most rare and precious diamonds are. In order to rate diamonds based on their color, a very precise scale has been developed : starting with the letter D (a white diamond, exceptionally colorless) to Z (a light yellow or brown diamond). All of the diamonds that we use have a D, E or F color. 
Cut (size) : Once created, the rough diamond is cut by the human hand that gives it a shape (round, pear, emerald cut…), the perfect proportions and angles that allow light to be refracted and have a scintillating sparkle. This precision work is an art. A well cut diamond will create spectacular light effects and show off its shine and radiance.

All of our diamonds superior to 0,5 carat are certified by gemology institutes like the IGI (International Gemological Institute). The jewelry that is made with diamonds of more than 0,5 carat are accompanied with an official certificate, like a diamond visiting card proving its quality.
