Lab diamonds
Lab grown diamonds offer an ethical and cost-effective alternative to traditional mined diamonds. Lab grown diamonds are grown in a lab by emulating the conditions that exist in the earth to form natural diamonds.
​
Two techniques are used to make lab diamonds, High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). Both methods are designed to replicate the normal conditions under which diamonds are formed naturally resulting in diamonds that are physically and chemically identical to natural diamonds.
​
The HPHT method involves placing a small diamond seed (a tiny fragment of natural or lab-grown diamond) into a chamber with a carbon source, typically graphite, and a metal catalyst. The chamber is then subjected to extreme heat and pressure. The high temperature and pressure cause the carbon to dissolve in the metal catalyst. As the temperature and pressure are carefully reduced, the dissolved carbon forms on the seed crystal, gradually growing the diamond.
​In the Chemical Vapor Deposition (CVD) method, a diamond seed is placed in a chamber filled with a carbon-rich gas, such as methane, and heated to high temperatures. The high temperatures cause the gas molecules to break down, releasing carbon atoms. These carbon atoms then deposit onto the diamond seed layer by layer, gradually growing the diamond.
​
​The CVD method allows for precise control over the growth process, which can influence the diamond's clarity and colour. ​The majority of our diamonds are produced using the CVD method.
