Lovely old Native American ring, sterling silver, tested, with coral next to a nice silver leaf, ring is signed H. SL and a small IM, and below cSc. We have found one source showing this was made by Navajo Silversmith " Helen Slim " who was also a master silversmith for the Old Canyon Silver Company and is from the Sanders, Arizona region . Ring is size 5 and in good condition. Coral is polished but may be natural color and has a lovely patina. Ring top measures 1 & 1/8" 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.
