Hand made dichroic glass with black onyx and Czech glass. I've taken layers of glass and fused them in the kiln to give this 2 x 1 inch pendant loads of depth and dazzle. The necklace is 17 inches long with a gold filled , heavy duty magnetic clasp. The clasp is monster strong and allows for easy on and off. (but only when you want) Perfect for that holiday gala or that little black dress.
