Navajo Signed Vintage Inlay ring multistone sz 10.25 (1115)

Navajo inlay with Onyx, Mother of Pearl, Turquoise, Jet & Coral. Bead and feather setting and beautiful stampwork around the band. The ring is signed but I cannot make out the mark. Unisex. Sz 10.75. If you run your finger over the inlay, the jet section sits a bit lower than the other stones. Not noticeable otherwise.
