Fabulous vintage and very unique pendant made from a large green real shell and on a 24" Milor Italy sterling silver herringbone chain.   The green shell is wrapped in squiggly sterling silver wire and there is a silver clam shell charm applied to the front.   The shell is just over 2" high and 1-1/2" wide and deep.   Necklace weighs 42.71 grams.   Very good condition.
