Swarovski Crystal Beaded Sterling Silver Chain Necklace Silver Tone Heart Clasp

Vintage Swarovski Crystal Beaded Sterling Silver Chain Necklace Silver Tone Heart Clasp. I think someone changed out the clasp on this necklace because I can't verify whether it is silver. The chain, however, does test as silver. The crystals are AB crystals. Swarovski made a necklace exactly like this but the clasp was different. Pre-owned, this vintage necklace is in excellent condition. Measures 16.25" - 18" long. N621
