I have been trying to find out information on a silversmith named C.M. Yazzie. I have a concho belt with 10 conchos each one has three blue turq. Stones in the center and 4 red coral stones on outer. Each one has an A and number from 1 to 10 on the back. First concho is stamped with C.M. Yazzie. Needing info on the belt itself and the maker

Navajo Artisan C. [Charles] M.[Mike] Yazzie

He did not sign his early work as he does today.. Known as "One of the best Silversmiths of that Era" (ARIZONA HIGHWAYS)

He not only worked with Turquoise he did exceptional Inlay work which was then very unusual for a Navajo Silversmith as Zuni's primarily used this technique.. I would say his Inlay Work was as good as the Great Zuni Silversmiths and Lapidarist of his day.
