Old Navajo Indian Silver Bench & Kingman Royston Turquoise Nugget Beads Necklace For Sale

Being offered is a vintage, Navajo Indian made jewelry necklace. The necklace is crafted from some nice size turquoise stone nugget beads. There looks to be a mix of predominantly Kingman turquoise, along with some Bisbee, Royston, and other types of turquoise. I have not tested the silver bench beads but believe them to be plated and not sterling silver. The necklace shows typical age related wearing but is in nice shape for its age. The necklace is approx. 22 1/2" long. The necklace weighs approx. 81 grams, and estimate the turquoise stones to be approx. 375 carats.
