Here's a pendant with an abstract design in overlay. It's apparently handmade. An underlined W is scratched onto the back; that's the only mark. We think the pendant might be sterling because of the overlay, but we haven't tested the metal. The chain it hangs from is an ordinary, inexpensive one. Pendant measures approximately 3/4 x 1-3/4 inch; chain is about 25 inches. Good condition with some light wear. Unknown origin; it might have been made for a silversmithing class or something similar. See more pictures or purchase from http://tinyurl.com/jytllxq.
