Custom Jewelry Proudly Made with Lab Grown Diamonds

Ada Diamonds offers the world’s most brilliant, conflict-free fine jewelry featuring diamonds grown in a laboratory. Lab diamonds are pure carbon, can vary in quality and price, and are able to be graded, appraised, and insured, just like mined diamonds. All of Ada's lab diamonds are optimized for cut and brightness, will be eye clean, absent fluorescence, and of exceptional quality. If we wouldn't wear it, we won't sell it.

Loose Diamonds

Ada's sustainably cultured diamonds have the same crystal structure, chemical composition, optical properties, and physical properties as a mined diamond - carbon atoms arranged in a cubic crystal structure.
