Dual-Grading Reports
Unlike other precious gems, each Cupid’s Ideal diamond holds a dual-grading system. Both the GIA (Gemological Institute of America) and the AGS (American Gem Society) have united to provide the most detailed grading report to date.
GIA’s Triple Excellent Cut
Cupid’s Ideals are graded ‘triple excellent’, meaning they reach the highest level of Cut, Polish and Symmetry. By combining these three elements, our cut is a benchmark for superior diamond quality.
AGS Graded Light Performance
The AGS, unlike other labs, has a specific method to measure a diamond’s light performance. This is based on three factors:
Brightness
- The intensity of white light, with minimal light leakage.
Fire
- The boldness and distribution of spectral colours.
Contrast
- The balanced pattern of dark and bright areas.
Through careful observation, an expert can evaluate a diamond’s capacity to reflect light. The diamond is then graded on a scale of 0 to 10 starting at ‘ideal’, which is zero, and ending at ‘poor’, graded 10 on the scale.
