black Pendants with opal and malachite inlay and set in sterling silver bezel

Beautiful vintage black pendants set in sterling silver (some gold toned) needs some love. They need to be reset into the rings and cleaned up (for some of them). Otherwise, absolutely stunning -- all different sizes and images made from different stones like opal and malachite. No brand. Last photo shows the typical black back. Sold as a set, or individually for $150 each just let me know by you messaging me.
