At Optimum Diamonds, we are proud to satisfy the needs of many premiere jewelers and sophisticated collectors. Each stone in our collection comes with a report from the Gemological Institute of America's (GIA) to certify each stone is a natural color.
Our extensive collection includes some of the rarest colors on nature's palette: Red, Blue, Orange, Argyle Pink Diamonds, and the largest collection of rare natural green diamonds in the world.
