Birdseye Kingman Turquoise Ring by Calvin Martinez, Navajo, Size 8.5

Calvin Martinez, a Navajo silversmith known for his bold and precise stampwork, set this large oval birdseye Kingman turquoise cabochon in a heavy sterling silver shank with deeply impressed geometric stamp patterns. Birdseye Kingman is a highly collectible variety of Kingman turquoise from the Kingman mine in Mohave County, Arizona, characterized by circular matrix patterns resembling bird eyes — formed when pyrite nodules oxidize within the host rock. The combination of birdseye matrix and heavy Navajo silversmithing makes this an exemplary piece of contemporary Southwest jewelry. Ring size 8.5. Available exclusively through Turquoise Mustang.
