Lab grown diamonds are graded and certified using the same process as mined diamonds as they feature the same optical and physical properties as a natural diamond does.

A diamond is judged by using the 4c’s- cut, clarity, colour and carat. Basically, the diamond is judged by how well it has been cut down from its raw form into a jewel, how flawless and clear it is, and its size. At Decent, the gemologists independently grade each diamond grown in the lab which determines its quality and purity.



We believe in offering a product our customers can be proud to wear. Extracting the raw diamonds from mines is a hazard to the workers and even to the earth which contributes to violence, human rights abuses, poverty, environmental degradation and many other issues. We are passionate about creating conflict-free diamonds that are produced in laboratories using modern technology with non-toxic means. We maintain responsible and safe labour practices.
