Are lab diamonds gem-quality stones?

No human rights abuses
Sustainable and Ethical

Lab diamonds are gem-quality stone . Now the environment in which a diamond naturally grows can be recreated above ground in a laboratory. According to the GIA (Gemological Institute of America), laboratory grown or factory-produced diamonds have chemical and physical properties that correspond to those of natural diamonds. These diamonds are being graded by the GIA (Gemological Institute of America) like natural diamonds using the 3 “C’s: color, clarity, and cut and are less expensive than diamonds from the ground.

According to Tenoris, a jewelry analytics company, in December 2022 15.7% of all engagement rings sold in the US were lab diamonds.

A big question that concerns diamond miners is will the FTC allow lab diamonds to be called “cultured diamonds”? Naturally, at stake is the diamond producer business and they don’t want the term “cultured” applied.

When pearls were produced by inserting a small seed into a mollusk and grown like natural pearls the term “cultured pearls” was allowed.

How do lab diamonds differ from cubic zirconia? They are chemically different.

Three websites with more information are:

Gemesis – “A diamond created by Gemesis has the same physical, chemical and optical properties as a mined diamond. It is, in fact, a real diamond.”

Chatham –  “Chatham does not make gemstones, we control environments in which crystals grow naturally.”
