*lol* it seems that diamonds are traced approx. 10 times a year *g*
I didn't know that diamonds are so popular :-)
Well: my story is: I was looking for something completely different (already
forgot what exactly) and fell over a diamond-ideal-cut-property-picture
showing exact properties of the thing. It was interesting and so I continued
looking for exact physical properties of a diamond (especially IOR) which I
found rather quickly.
You can imagine the rest :-)
BTW: most pictures I saw in these threads were pretty deep cuts which don't
reflect properly. Strange. Either all made the same mistake or they all used
the same model?

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" ?

BTW: you got me wrong. Read the subject before the text. The "good job" was
NOT meant for the diamond but for the PoV/MegaPoV DEVELOPERS.
All clear?

I'm clear. I understand that you were not bragging about the diamond.
I meant what I said, though. Creating a convincing emerald material would be
a serious accomplishment, and worth bragging about.
