1. Setting the stage

The Chemical Vapor Deposition (CVD) diamond growth process begins with our high-quality Type IIA ‘seeds,’ or thin slices of diamonds. Once placed inside of our proprietary growth chambers, we introduce a tailored mixture of carbon-rich gases, heating them to create a greenhouse-like environment mirroring natural growth conditions.Through the art and magic of science, of discovery and evolution – over time, pure carbon organically bonds with each seed, atom by atom, resulting in the growth of new crystalline structure.

3. Diamond in the rough

Once the rough diamonds have reached their optimal height, our team of scientists remove them from the growth chamber, proceed with quality assurance testing, and shepherd the best-of-the-best through to our finishing stages.

Each Cosmos diamond is then planned, cut and polished by our expert artisans to amplify its brilliance. Finally, it is graded and certified by the world's leading independent laboratories, responsible for assessing the top mined gemstones in the world.
