AGS Proprietary Light Performance Diamond Quality Document

The Fire & Ice difference is recognized by the American Gem Society (AGS) with its proprietary Light Performance Diamond Quality Document.

Every Fire & Ice Diamond receives the highest grade possible from the AGS, AGS Ideal 0 for cut, AGS Ideal 0 for light performance, AGS Ideal 0 for polish, AGS Ideal 0 for symmetry, but the Fire & Ice standard is far more precise than required by the AGS for a 0 Ideal cut grade.
