The creation of a lab-grown diamond
Through the magic of technology and the wonders of science, our diamonds are born from the same forces as deep within the Earth. Coast, in Russia and in Asia, using two technologies.
The first technology is High Pressure/High Temperature (HPHT). This method replicates the conditions in which diamonds formed deep within the Earth, billions of years ago. A microscopic diamond seed is put into a press, then subjected to extremely high pressure and a temperature in the region of 1,500°C (2,700°F). Carbon atoms attach to the seed, causing it to grow, very slowly, over a period of several weeks.
The second method is Chemical Vapor Deposition (CVD). It also replicates the conditions in which mined diamonds are formed. The diamonds are created in a low-pressure atmosphere using hydrogen plasma, which causes the carbon atoms to crystallise into diamond.
It takes between three weeks and a month to obtain a rough diamond, which is then sent for cutting. Once the diamond has been cut, its colour, clarity and carat weight are revealed. The stones are now ready to be mounted in our jewellery studios, in France and Italy. Thanks to this short and transparent supply chain, lab-grown diamonds are priced lower than their mined counterpart, costing 30% to 40% less.
