I could make a thing like that too. But I was going more weird science fantasy and thinking mythalars that look like dice. Still haven't got the textures or emitters working as I wasted a lot of time trying to get my work into blender and exported and realized that I forgot how to do all that. Its been a year since I made an NWN model that worked in game, and all the ins and outs of blender and MDLs are hazy to me. I also haven't got the textures the way I want them for NWN. I had forgotten that I can't bake procedural textures which rely on reflection and refraction etc... to look good.
Models however are low poly. All are under 500. The stand is 392 triangles. The dice range from 4 to 36 triangles. I forget what that lump comes in at, but its less than 100 tris. Maybe 50.
So here's the last renders I made in the morning yesterday in Cheetah3D with the procedural textures before I got distracted wrestling with the above and then walking away to spend time with the kids:
---edit---
might as well share my process of working on the stand texture. I basically set up a procedural material, apply it to the model, set up ambient lighting only, and then bake it all to a texture. It allows me to try a dozen variations. I had lost a lot of time here because I made the mistake at first of including the affects from an HDRI and couldn't figure out why nothing looked like I expected. Eventually I got on a roll and cranked these out. It required me to make a couple separate black and white (value only textures) that I made from photo references of metal and reworked. What you can see below used three different textures, and then procedural filters. Most totally suck. But I'm using this one I think:
I was ultimately going for a hammered metal. This is not exactly what I wanted as it looks more painted than like black, wrought iron. But screw it. Good enough. You can also see that the crystal will not be included. Its a waste of draw calls to have too many textures, but I think it makes the model easier for others to modify if the crystal and the stand are separate.
The rest turned out like this.
