Older Native American silver tested sterling and turquoise ring, we don't think it is signed, at the base of the shank there are two marks in the silver that look like a tiny JR, but could also be marks where the ring was sized or tested, so consider it unsigned, which would be normal anyway for an older piece. The turquoise has beautful matrix and inclusions running across it, the line is not a crack; stone is highly polished. May or may not have been treated. The ring is size 9 and the top measures 1 & 1/4" long. I collect Native American jewelry, especially rings, and when I wear them, I wear four on each hand, meaning 8 rings in all sizes too. And finally my collection has grown too big to keep all of them. A lot of our listings are from my personal collection, all hand selected with care.
