This sterling Silver pendant has a gorgeous natural stone. The color is outstanding. I searched natural stone sites to try to identify it and I believe it is a stone called charoite. It could also be tanzanite but those stones seemed to have some gray in them and this pendant does not have any gray. Pendant comes on a sterling chain with a spring ring clasp. The chain is 24" long and marked Sterling Italy. The pendant is just under 1 3/4" top to bottom including the bale and is marked 925. Necklace weighs about 20 grams and has some old patina. It is in excellent condition.
