This one-of-a-kind necklace is 21.5" long, but is technically adjustable in the sense that you can attach the clasp anywhere along the chain to make it shorter.  The chain is sterling silver.  There is a central porcelain charm (by White Owl Ceramics) depicting a bird/crow in black, along with a sterling silver granulated panel accent. The two elements together measure 2  7/8 x 1 3/8".  This is an elegant and unique piece.  Care should be taken, as porcelain is fragile and could be broken by dropping etc.
