They look awesome with the caustics and all. Seems like diamonds are LOW POLY TRIANGULATED items take that

looking into some more custom gems, but for now I'm focused on trying to make some less than perfect materials for gems.   some of the most beautiful gems I've seen in person, have been the kind with impurities trapped in them, or dirty refractions.  Some of these, like opal for instance, would require actual geometry in the interior and a lot of different elements and materials going on.  I've created a new gem material, and I'm tweaking it to see what I can come up with.  This is what I have so far.  A little interesting, may have potential.   

These are all just quick preview renders to keep track of the various material versions.  although these are only a fraction of them.  In these I am experimenting with using a dielectric and gem material occupying two of the same model in the same space to give a compounding effect.
