Brilliant, Bespoke

Ada Diamonds is proud to use laboratory-grown diamonds in all of our fine jewelry. Our cultured diamonds are chemically and structurally identical to mined diamonds, but socially and environmentally superior to Earth-extracted diamonds. Ada Diamonds curates the highest quality diamonds for our inventory and cultivates commissioned diamonds from donor carbon for the ultimate in bespoke jewelry.



Of the highest quality

Ada Diamonds designs our jewelry collections with artists worldwide, with the highest quality lab diamonds and ethically sourced metals of the highest purity. Every piece fabricated is cast and set in the United States by award-winning fabricators.

"Man-made diamonds are now better than mined.
Here's why:" —Fortune, 2016
