This is a mathematically exact diamond round cut in 3ds format.
Diffuse is black, fresnel reflection and refraction 100% white, IOR 2.417 for diamond.
Max reflection/refraction depth should be at least 8-10 or set exit color to white.
I used a few 8 sided cones in Rhino with the Blue Nile diamond ratios to figure out the angles. If the cut angles are off even slightly then it completely changes the look and you realize exactly why diamonds have to be cut this way.
I've also done it in max but it takes longer to be precise enough since you have to actually do the calculations. You just boolean/intersect a few 8 sided cones. 2 on the base and 4 on the top at various heights and angles, ,22.5 and 11.25 degrees rotated.
The first cut would be an 8 sided cone 100x100 then clone and rotate 22.5. Drop the second cone height to around 85 and boolean/intersect. That's all there is to the 1st top cut and the base is just a mirror of that with the 85 height cone changed to around 98. The rest of the top is more of the same but it gets slightly more complicated.
I might do a max tutorial on it because it would be a good and fast modelling excercise. It takes about 5min in max compared to less than 60sec in Rhino.
True it would take a lot of time, but if your creating something based purely on mathematics its not hard at all. As long as you know and understand all of the math your using then you could create any shape easily it would just take a lot of time and effort but its not something that requires any artistic value. Nice diamond though but what I really want to see in reall life is for them to put a diamond made of white gold but paint it black then put it inside another diamond. Now that would look amazing, but I suppose seeing it in 3d will have to do for now.

Daily Literature Deviations is a group that is dedicated to bringing literature to the forefront of the deviantArt community. We attempt to accomplish this by daily featuring Literature artists from around the community that deserve the recognition, but are not getting it.
Each day we will feature 5 deviations from the Literature categories in a News Article. In order to support the artists that we feature, we ask that you the news article as well as check out the individual pieces. We understand that each day you may not be able to check out each and every one of the pieces, everyone has their own things going on. We just ask that you make an attempt to help support the growing Literature community.
Although `DEVlANT joined our community only a year ago, he's made sure to make his mark in as many ways as possible. From extensive bug testing around the site, to heading up the now infamous #devBUG Group, Martin's always eager to get involved. His inquisitive mind and enthusiastic personality is reflected in every part of the community which he reaches out to. Always eager to bring suggestions and feedback to us in a positive way, `DEVlANT shows a maturity way beyond his years. It's with great pleasure that we award very first Deviousness of 2010 t...

seriously, amazing precision, and it's so pretty
and I didn't comment on the swans, but .. also beautiful .. so cool and glassy

Show me an artist who is not insane.
And I will show you one with no creativity
