A beautiful vintage sterling and saw tooth bezel set natural turquoise cluster ring marked Sterling and PA which I believe is the hallmark of Navajo silversmith Paul Arviso. I purchased this ring from the original owner who bought it in Arizona in the 1970's. It is a size 5 1/2 and the face of the ring measures 1 1/4" long and 1" wide. Fine original condition with no chips or cracks to the stones. It is an impressive ring.
