I only just now saw both your diamond renders. Especially these last
ones look really good.
I have to agree on what Jaime wrote, most images of brilliants I've
seen look more like the image he linked than the one you posted.
I was trying to do some brilliant cut diamonds two weeks ago and managed
to google up some extra information:
The ior and dispersion settings should be correct, reflection is a bit
off I think; I found information (don't have the link but can probably
google it up again if you need it) that diamond reflects around 17% at a
0 degree incident angle and nearly 100% at a 90 degree angle.
I don't know how much influence this has on the output image but I
remember it made the my renders better after adjusting the reflection
settings, allthough it could be I fiddled with another knob and this had
nothing to do with it.
I included an image of one of my renders ( I don't have the source for
this exact scene any more as I continued to play around with it, but I
still have the settings for the diamond texture, interior and finish)
Mind you, I think your renders look a lot better, the colors in my
version are way to flat(?) and seems to be to harshly lit, but I do like
the characteristic blue and yellow streaks (scintillation ?).
I hope this helps any and is not just a wast of bandwidth ;-).
