This is a beautiful crystal necklace pendant. It has high transparency and reflects light with a sparkle. The metal part is stamped with 18kgp. I believe it is probably silver 925, but the metal material is unknown. I think it can be arranged in various ways, such as a pendulum, earrings, or hair accessories. A transparent crystal multi-faceted pendant.
