This is a David Yurman 18k yellow gold amulet charm pendant with an octagonal Amethyst stone. It’s absolutely beautiful. The bale opens to accommodate a chain up to 3.6mm wide. I show it on a DY 3.6mm box chain necklace and a DY 18k baby box chain for illustration purposes only. This listing is only for the amethyst amulet. This piece is in excellent pre-loved condition. The clasp works perfectly. It will be authenticated by PoshMark.
