This beautiful piece comes from my own collection. It was purchased at the Tucson Gem show in 1990. I've hoarded and admired it long enough time to share. It measures 5.25" long. The bail is stamped 925 and is large enough to accommodate a medium to large chain or omega. The onyx is pave set and the oval stones are channel set. all of the framework is set with marcasite stones. The amethyst and peridot the red and blue I assume are zircon. The stones are open backed with the exception of the marcasite. This gorgeous piece measures precisely 3" wide. It is of course the only one I have - once sold there won't be another for me. Will ship via USPO with delivery tracking.
