Vintage Fluorite & Amethyst Bead Necklace

Beautiful vintage fluorite and amethyst necklace. Necklace also has what I think to be shells towards the closure. Closure is sterling silver and marked 9.25 .No makers mark. Necklace is on the heavier side. Possibly missing some a couple of small beads in the back but doesn't look obvious. Necklace is a total of 22 inches from end to end. Preowned vintage condition. Minor wear but expected. In vintage condition (very good). Bundle 3 or more items for 15% off and feel free to make a fair offer.
