This is a cut necklace made of natural crystal (rock crystal). It comes with a case and warranty from Eigado. The clasp is marked SILVER. It's a shorter length, so it gives a neat look around the neck. There is no verdigris on the metal parts, including the clasp. The overall condition is good. There are no noticeable damages, but please understand that this is a used item, so there may be minor imperfections.
