Vintage Navajo J YAZZIE Signed Silver Malachite Cuff Bracelet EUC

This rare vintage cuff bracelet is a true work of art. signed by Navajo artist J Yazzie, it features a beautiful oval-shaped malachite gemstone set in silver. Malachite presents loyalty, fidelity and protection. Perfect for all occasions, this bracelet is a unique addition to any jewelry collection. The piece is made of high-quality gemstone and metal, with a silver base metal, I was told it is sterling silver, but I am not seeing anything stamped 925 on it, I saw this same bracelet on EBay also saying it is sterling silver with no stamp. I don’t want to make any false claims though. Inside of cuff measures approximately 5” tip to tip, plus a 1 1/4” gap. Stone measures 1” tall, 3/4” wide. It is a vintage piece from the 80’s, in very good condition, some natural wear. I try to take plenty of pictures to show details. I am happy to answer any questions. Thank you for looking!
