This handsome ring is vintage circa 1940s or 50s. It is fashioned from sterling silver and has a dark green blue stone set in it that I am calling turquoise but it may be something else. The ring is a size 6 and measures 1 3/8 x 1 inches at the top. It has an arrow design etched on the sides and it is stamped Sterling on the band and on the top. It comes from the same estate of American Indian jewelry that I have recently acquired.
