Here's the final.
It's a bit hard to tell, but there is a light inside the top piece to highlight the ring.
I put this ceramic stucco on little pieces of chipboard to look like stone blocks and then applied it to the model, a stone veneer if you will.
The stucco had a very bright gray color that clashed a bit with the gold. I tried to paint over it, but the paint was too thick and it covered the texture. Last minute I had the idea of using my bronzer to tone down the color. The powder was great because it kept the texture intact and gave it a warmer color. Bingo.
