I did this piece in sterling silver and anodized aluminum. I figured that since I still had some leftover of the colored rings, I might as well try. It worked out well, even though I'm not personally a fan of pink. It's not completed in the photo, though I did complete it. The photo is enough for you to get the idea of what I did. There's no clasp... you just roll it over your hand, onto your wrist.
