Refraction of Light by Diamonds |
||||||
 |
||||||
|
||||||
| The brilliance of diamonds is due to their high refractive index, a measure of how strongly a transparent material bends light rays. The skill of the gem-cutter lies in angling the facets of the stone so that each light ray entering it is reflected many times before it emerges again. | ||||||
