A large and distinctive  turquoise and mother of pearl silver ring.   The ring has a very large oval shaped head to it set with hand cut pieces of very vibrant American mined turquoise and a very silvery white mother of pearl piece.  The design is that of the Zuni Native American tribe, and was made by a jeweller from this tribe.  The Zuni tribe, now located in Northwestern New Mexico, was the second Native American group to learn Mexican silversmithing techniques. Navajo artist Atsidi Chon initially taught the art to a member of the Zuni tribe. Their artisans refined the Navajo 'cluster work' technique, characterized by a series of shaped stones set into various bezel settings. This 'cluster work' later evolved into the more intricate petit point and needlepoint styles.  A variety of bold and colourful stones are cemented into channels created by soldering pieces of silver to a backing plate. The stones are then polished flat, resulting in multicolored designs with  veins of silver running through them.  The ring is bears a makers signature on the inside, but it is worn, and not legible.  The ring is a size 10.  This ring, and any other can be sized to any required size.
