High quality Turquoise Necklace. Vintage 1990. Sterling clasps

This necklace was given to me by my late in-laws, who purchased it from a high-quality Southwest art gallery. I don’t have any authentication for you but pieces of turquoise are extraordinary. Each one is different. They are all oval in shape. There are approximately 128 pieces of turquoise making up for strands. The necklace can be worn as a short choker type necklace at about 14 or 15 inches and it can extend to 17 inches. Sterling silver . one of the sterling silver cones that make up the end of the necklace has a very slight dent in it for full disclosure. Thank you for looking feel free to ask questions.
