I love using mixed media in my polymer clay creations

One of the reasons I wanted to start Things Crafty TV is that I have so many mediums I love to work with other than polymer clay. Polymer clay is my first love so I try to find other mediums that I can manipulate so that I can use them with polymer clay. In this photo I am showing you the center of what will be a pendant. I have used 4 different items to create it, while you may have never thought to pair these 4 things together I thought the effect was that of faux dichroic glass. Can you guess what I used?
