Vintage 14k & 18k gold watermelon tourmaline pendant necklace

This is a vintage pre owned pendant necklace in excellent pre owned condition showing some moderate signs of gentle use and it looks like one bead is missing towards the clasp. Please see all photos.  Genuine watermelon tourmaline gemstone naturally colored bezel set in authentic 14k yellow gold. Faceted rondelle watermelon tourmaline beads wired onto 14k yellow gold for a length of about 17-18 inches with extension chain. Gold has been acid tested for purity verification. I believe this originated from The Nature Company stores in the 80’s -90’s era. Total weight is 12.33 grams. Lobster clasp is 18k yellow gold and stamped 750.  Pendant measures about 10x22 mm. Not papered as this was an estate purchase and paying for papers would increase the price significantly. This is a one of a kind heirloom type of piece to add to your collection!
