I just found this, and I thought it was so beautiful that I had to put it straight on here. This is definitely one I will try (once that damn lottery announces me as a winner), and while it looks complex and gorgeous, I think it's something even I can accomplish :)
Additional tip from the maker of this pendant: "If you are going to fracture (fry) marbles per the instructions I provided, you'll need to find marbles that are made up of transparent glass (whether clear or tinted). That way you can see the facets. If they are opaque (where light doesn't go through them), they don't work. Good luck with your project. "
