Vintage Navajo Rainbow Man Brooch Sterling Silver

Vintage Navajo Rainbow Man brooch pin. Sterling silver with mother of pearl in a light pink tone on the left and an iridescent white tone on the right. Stamped pattern with etched detail on face. Signed “KB Sterling” on back, a stamp used by multiple members of the Begay family, but the materials and craftsmanship are likely of Keyonnie Begay. Extremely rare piece acquired from the estate of Southwestern Native American jewelry collectors. 2” length. 1.25” height. Excellent vintage condition.
