This pretty cross is sterling silver with 3 different stones, but I'm sorry I don't know what they are. The center is an opaque, clear-ish white, the rectangle stones are a brownish clear and the small teardrop shaped stones are a light opaque gray. The pendant measures approx. 1.5" x 1.5". The chain is 30" long with a lobster clasp. If you would like the chain to be shortened, please let me know what length you would like and I'll be happy to make the adjustment. It is in excellent condition with no flaws. Please see pictures for full measurements, fabric content and cleaning instructions. Smoke-free, perfume-free home Offers welcome!
