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 am still trying to find out more details about this piece, but I believe it is from the Swarovski Signature Jewelry collection circa 1996-1998.

It appears to be new, never worn, and comes with a blue Swarovsk gift box.
