Scientific research dates back to the 1950s, and it is only very recently that gem quality stones have been obtained for jewelry.
By taking over from nature, Human in turn allows the growth of a crystalline mesh made up of carbon atoms of immense hardness. Lab grown diamonds have the same physical, chemical and optical characteristics as diamonds crystallized underground or in space. Only their origin differs.
Each crystallized stone is unique and is individually cut.
Lab grown diamond carries with it a modern history of innovation and sustainability.
Two manufacturing methods are distinguished:
HPHT (High Pressure High Temperature) method : High Pressure High Temperature.
CVD (Chemical Vapor Deposition) method : Chemical vapor deposition.
Lab grown diamond exists perfectly colorless, but also in all the colors of the rainbow, they are called FANCY COLORS.
A true identity card for each stone, the scientific gemological certificates are independent.
They precisely evaluate the 4C's Carat, Color Clarity and Cut (carat, color, purity and
size) but also the proportions, symmetry and polishing of each diamond whatever its origin and according to strict international standards. These certificates are crucial because they provide reliable and unbiased information to consumers and industry professionals. They are always written in English.
There are three world-renowned laboratories that are references:
The GIA - Gemological Institute of America
IGI - International Gemological Institute
HRD - Hoge Raad voor Diamant (Higher Diamond Council in Dutch).
International gemological laboratories exclusively use the terms Lab Grown Diamond for Laboratory Grown Diamond. Each certificate is numbered and all diamonds from Exquisite Lab Diamonds are laser engraved with this unique number on their girdle preceded by the words LG for Lab Grown. This engraving is invisible to the naked eye.
