Zuni Native American ring of sterling silver with turquoise, signed Effie C for the late Effie Calavaza, Zuni, her trademark double snake design, size 9, very good condition. The turquoise nuggets are very large with nice matrix, may have been treated, but have a natural look, we are pretty sure these are Sleeping Beauty turquoise. Tested sterling. 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.
