Vintage Retro Dichroic Glass Pendant and Necklace. Both pendant and snake chain are sterling. Pendant is approximately 1/2" wide x 7/16 high. Snake sterling necklace chain is 16" long. Flaw: the back of the pendant has some scratching. I do not know the weight of the chain necklace. I have another sterling necklace in my closet - bundle for savings.
