Excellent Condition. Necklace measures 17”. All natural gemstones- I am not a gemstone expert so I would prefer not to guess what these are. I can guarantee every piece is genuine stone. All cold to the touch. Really nice . Check out other items in my closet! Over 2,000 items- mostly jewelry! Bundle for the best discount! ( 20% off for 2 or more items). Questions?
