This is an extremely rare vintage piece from VSA. NWT it is a two tone necklace from the Tres Luches collection. The chain links are sterling silver and the masks are in brass. It can be worn long or use a VSA “extender” to create a two-layer look. I have never seen another piece like this. Very few items from that collection are ever available. However I do have the matching ring in my closet. Purchase together for a bundle discount.
