18 inch LONG WITH A 2.5 inch DROP PENDANT HANGS FROM THREE STRANDS STAMPED STERLING AND A HEART HALLMARK. IT HAS AN ART NOUVEUA LOOK TO IT BUT IT WAS NOT PURCHASED AS AN ANTIQUE. I PURCHASED THIS MYSELF AT A WOMENS CLOTHING STORE IN THE 90's. I BELIEVE THE STONES ARE SEMI PRECIOUS AND A PRETTY PIECE.
