This is a necklace I made my mom for christmas. The main pendant is quarters laminated and patterned. When polished they show the layers of copper and nickel (no one start berating me telling me it's illegal, I'm perfectly within the law as long as I don't make any profit from it, I've researched this already). The inner pendant is an opal earring my Mom got on sale for this exact purpose. I drilled a small hole at the top, stuck the pokey thing through, and glued it in.
P.S. that's my sister modeling it, my neck is to rough and dirty, and I look to manly to wear a girls necklace.
