Certified Diamonds

Our selection of certified diamonds is carefully inspected and graded according to the strictest guidelines. You'll receive an official diamond certificate with each purchase, which reports the quality and grade of a stone as determined by gemologists. It provides a blueprint of a loose diamond and includes the stone's exact weight, cut, measurements and quality, too. Be sure to check out our diamonds certified by GemEx®—their powerful, patented BrillianceScope™ Analyzer tool gives multiple measurements on how light reflects and refracts through the stone to determine how bright it sparkles. You'll also find jewelry with diamonds certified by the Gemological Institute of America (G.I.A.), Gemological Science International (G.S.I.), American Gem Society (A.G.S.) and International Gemological Institute (I.G.I.).
