What is the ASET® Map on an AGS Ideal® Report? 

The Angular Spectrum Evaluation Tool (ASET®) technology was created to be a visual guide of a diamond’s cut grade. It is generated from software that traces individual rays of light to create a “map” of the diamond’s performance. The ASET® Map displays optical symmetry, physical symmetry and optical efficiency in color to show the craftsmanship of the diamond’s cut.

The map features three colors that give you information about the light performance of the diamond. Red indicates the brightest areas of the diamond – areas that attract the brightest light from above. Green also indicates light return, but from an indirect source which is not as bright. Blue indicates a contrast pattern of dark reflections. Together, the areas of red, green and blue provide a unique “thumbprint” of the diamond, documenting its light performance and beauty.
