Chan Luu Faceted Black Gemstone Ball Drop Earrings

Chan Luu Faceted Black Gemstone Ball Drop Earrings Sterling silver French hooks, 1" drop. I am not an expert in gemstones, but my guess is they are black onyx. These are pre-owned in excellent condition. I purchased them while on a business trip 8+ years ago, but I don’t remember ever wearing them. Ships quickly from smoke-free and pet free home!
