La Bolivianita Necklace w/18k Yellow Gold Chain

18K Italian gold chain with La Bolivianita pendant, also in 18K gold. Length of chain: 17.5 inches. Precious stone: Ametrine or Bolivianita. Ametrine, also known as trystine or by its trade name as bolivianite, is a naturally occurring variety of quartz. It is a mixture of amethyst and citrine with zones of purple and yellow or orange. Almost all commercially available ametrine is mined in Bolivia. New without tags! I purchased this item from the manufacturer last March in Bolivia. .
