Fire & Ice Diamonds are the result of extensive research conducted by the Gemological Institute of America (GIA) and the American Gem Society (AGS) concerning the behavior of light in a diamond. Building on this new understanding of the science of light return, Fire & Ice Diamonds are cut to precise angles and proportions to maximize the radiant light and sparkle emerging from the top of the gem.
Bigger, brighter and whiter, even compared to other Excellent and Ideal cuts, every Fire & Ice Diamond reaches the highest standard for cut, proportions, symmetry and light return from the GIA, AGS and Forevermark grading laboratories. Fire & Ice Diamonds have a narrower set of acceptable proportions than GIA Excellent and AGS Ideal cut diamonds. Diamonds cut to the proper proportions will reflect and refract light in a vivid display of Brilliance, Scintillation and Fire.
