I just love this Serpentine stone! It is set in a Sterling Silver bezel cup with scalloped edges. I have added a little interesting shaped wire that lays over the stone. It also has a forged hammered wire that dangles below that gives the pendant a lot of motion. It is connected to an 18″ chain that secures at the top of the pendant so that the clasp becomes apart of the design of the necklace. The toggle is a large gauge Sterling Silver wire that has been hammered. The piece is all Sterling Silver. What is great about this piece is that there is only one! You will have the only one!
