Authentic old Navajo sandblasted cuff with genuine turquoise set in the middle

like many authentic Native American jewelry, there is no stamps of any kind but the process used to create this heavy, solid cuff provides a good amount of information. Sand casting is an arguous process and this style is sought after by many collectors. I'm not sure the silver content but definitely mostly silver. the cuff will not bend, no matter how hard you might try. It's definitely vintage and might more realistically be antique because this was made before silver jewelry legally had to be stamped. My best guess is about 100 years old or so. Great condition minor scratches here and there but the buyer can choose how to handle that if at all. Amazing patina too. The style and method of making the cuff is very very likely to be Navajo craftsmanship.
