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. 

 
 
 

"Synthetic diamonds are diamonds. They’re not fakes.
They have all the same physical & chemical properties of a mined diamond."
