Silver filigree.heart necklace

Silver in color. Not sterling. I haven’t tried to polish it bc I don’t want too damage it. It maybe vintage if not it’s a lil older. I can give this necklace as a gift if you purchase another piece. Used good condition. Does need a light cleaning. Please view photos as it’s your best description. 16 inches with 3 inch extender. Lobster claw. Maybe crystal or glass. I didn’t test stone. I do kno the metal is magnetic.
