Rather than offering 'dirt diamonds' that are dug out of massive holes in the Earth, Ada Diamonds proudly offers only laboratory-grown diamonds in our fine jewelry. 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. 

Ada's gemstones are graded on the exact same criteria as mined diamonds (the Four Cs), by the same independent gemological laboratories that grade Earth-extracted diamonds. Compared to mined diamonds, Ada's diamonds have fewer impurities and fewer defects. This makes Ada Diamonds whiter, brighter, and stronger than the vast majority of mined diamonds.
