Vintage Swarovski Crystal Pave Heart Necklace

This gorgeous necklace features a clear crystal pave heart pendant on a serpentine (?) chain. The heart measures approximately 5/8" wide and 1/2" high. The chain is approx 16" long with "SWAROVSKI" engraved on the clasp. The necklace is from the private collection of a Swarovski employee in the US. I believe it is from the Swarovski Signature Jewelry collection circa 1996-1998. It appears to be new, never worn. No box.
