c1950's Native American Overlay style Silver and turquoise earrings. These are extremely nice, unmarked other than scratched 33 on the back of each. My guess is the hooks were "cold soldered" later..
All precious metals are tested and guaranteed. A Native American jewelry piece referred to as "silver" or "ingot" is guaranteed to be at least 90% silver. I rarely use the word "sterling" when referring to older Native American silver or really any older silver jewelry as silver contents vary and "sterling" is 92.5% silver. No older jewelry is going to be exactly 92.5% silver, some a little over, some a little under. It wasn't an exact thing with handmade jewelry. I've seen thousands of pieces xrf'd to prove this. Bracelets are photographed on a 6" women's wrist.
