Diamond

My try to get the sweetest render of the “diamond” I made.
Got to love the warming effect inside it!

Nice start, but what makes a diamond shine brilliantly in real life is their very high IOR (over 2) and the intricate pattern of cuts a stone receives as it is turned into jewelry.

Right now, the IOR needs to be much higher and the mesh needs to become faceted with lots of small cuts.

I will keep that in mind, thank you for the feedback!

There are various ways of achieving dispersion effects. You have taken a traditional approach of adding three glass shaders.

There is an alternative that is quite a bit faster:

Will cycles get dispersion effects?

You can achieve dispersion a number of ways in cycles. The first and easiest method is to add three glass shaders. Each glass shader is set to either R, G or B - and the IOR is set differently for each one. This method is quite slow because you are using multiple glass shaders. The second method is to add a procedural texture - then drive the RGB and IOR values through it. If you make the texture size small enough - you’ll get the dispersion effect without actually seeing the texture. I al…
