GIA & AGS Certified Diamonds

Every diamond in Ritani’s vault is independently graded by one of the foremost gem labs in the world: the American Gem Society (AGS) or the Gemological Institute of America (GIA). Independent diamond grading ensures that each gemstone meets the highest standard of craftsmanship.


The Ritani Diamond Difference

From classic round cut diamonds to modern princess cuts and vintage oval shapes, our inventory holds many of the finest diamonds on the market.

Ritani diamonds are curated in the heart of Manhattan’s Diamond District, in the largest diamond factory in the U.S. Our select group of diamond cutters bring many years of education and experience to their work, as well as a deeply held passion for bringing out the beauty of rare gems.

These men and women have been entrusted with cutting some of the most prestigious diamonds of the decade, and their attention to detail is evident in every gem they craft -- from the tiny 0.10 carat diamonds brightening Ritani’s signature halo engagement rings, to a stunning 25 carat diamond masterpiece.
