Brass that I put through the rolling mill to get that cool pattern. Then I soldered on the three gemstones and set them in sterling silver. DalmatianJasper, Onyx and a Swiss Blue Topaz are the three gemstones. The double sterling chain with a few black spinels has been blackened and can be adjusted from 17-20 inches. It can be removed from pendant if so desired. The pendant measures 2.5 inches long and 1.5 inches wide. A kind of magical piece of jewelry that no one else will have.
