This is a very pretty necklace. The necklace and pendant are made out of 925 sterling silver. The necklace has a high polished finish. The design of the pendant is unique. The chain is 18 inches. The clasp of the necklace is a easy hook. It is made very well and is durable. By no means does this necklace look cheap. The gem is classified as a crystal. The necklace truly looks elegant. I have had no trouble with discoloration on my skin. You definitely can not beat the price!
