Yes, as many other topics it seems that
diamonds reappear quite often in these
groups.

I find the diamonds shapes and their internal
reflections very interesting. So I hope I soon
can find time to make some more diamond images.
(But there are so many other POV experiments
that I just have to do first...)


Here are IOR's for many real-world materials:

IOR_Isotropic.inc has IOR values for diamonds

It has been a while since I worked with
"perfect cut" diamond shapes, so I don't
quite remember if I was totally satisfied
with my shapes.

Btw.: Are you really sure that the girdle
lines should be "roundish" ?
