This is a two-strand long necklace made with onyx-style black parts and a silver-colored chain. The larger black parts are flat circles with cut surfaces. The smaller round parts are both glossy and matte, giving an elegant impression. I think it would look great with a white blouse or sweater. It's been a few years since I bought it, but I haven't had a chance to wear it, so it's in good condition. (The blouse in the fourth image is for reference only.)
