Pawn Sterling Silver and Turquoise Cuff Bracelet. This is indeed an unusually fine piece of sterling silver jewelry, obviously designed to showcase a rare gem. It hails from the Navajo tribe with simple design, as much of the best Native American jewelry tends. We believe it to be from the Easter Blue Mine in Nevada, though other veins of turquoise produce similar patterned material. Little rough is available today, and it is particularly rare to see such a large and fine specimen. The mineral Limonite is responsible for the splotchy brown characteristic. Yes, it is as blue as the photo suggests...a nice opportunity to own this quickly disappearing stone.
