Early Signed Navajo Turquoise Ring in Sterling Silver Size: 4

Early signed Navajo sterling silver ring set with 4 round cabochon turquoise stones. These stones are natural and have not been filled with plasticizers. They have uneven top surfaces. 

The shank is hand wrought with an early sunburst stamp decoration. Two cold chisel splits on each side. 

Size: 4 Face measures 7/8" long. Weight: 7 grams. 

Great Hallmark inside that may be an unpublished version of the mark of Lee Friday. If this is the case, this would be not Navajo , but Cheyenne/Arapaho. 

Tarnished and has a lovely patina from age.
