From article:
When light enters a diamond, the high refractive index causes it to suffer multiple total internal reflections, which is the reason for the brilliance of these gemstones.
Removed. The total internal reflection is not special to diamonds, nor is is a natural property of diamonds. The stone must be cuts specially to show it, and the same can be done with other stones (most noticablly with cubic zirconia, and rock crystal). I can't think of a useful way to put this that illuminates (har-har!) anything to do with refractive index.
!! Recommendation: phase velocity should be named v instead of v, which does not differ from greek letter Germendax 09:20, 3 Mar 2004 (UTC)
