I'd really like to render them myself adding more
halogen-lights around (more photons) - like in the Jewelers-shop.

Personally I prefer rainbow colours and the first picture :-)..

  Definitely better. Much more natural reflections and colors. Amazing!

> 3- real

  Perhaps is not a very good reference photo. Take a look at that other:

  Aren't these much more similar to your ones? :)

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 ;-).
