Fabulous and Bold Dian Malouf Ring in Sterling Silver and 14k. An Oval Black gemstone is bezel set east to west in a 14k Yellow Gold hammered setting. I am unsure what stone this is. It is not onyx but could be an obsidian. This stands up half an inch high on a thick sterling band that looks like a shingle pattern along the sides. This piece is a size 6. This is stamped inside DLM 14k and 925. This is in very good pre-owned condition with some scratching on the band.
