Comparison of Diamonds using Direct Measurement of Light Behavior
Light Behavior Image |  |  |  |  |
| Brilliance | 113 | 118 | 123 | 165 |
| Sparkle | 30 | 38 | 58 | 92 |
| Intensity | 114 | 120 | 162 | 302 |
Overall Light Behavior Grade | Fair | Good | Very Good | Excellent + |
Images shown above are of actual diamonds with different light behavior grades - ranging from Excellent Plus to Fair. The differences in images and measures clearly indicate which of the diamonds shown below has the highest light behavior grade. The optical patterns of light return add an interesting visual aspect which can be correlated to a diamond's actual light behavior.
