Old Navajo Sterling Shadowbox Bracelet with Green Turquoise and Coral

Old Navajo sterling silver stamp decorated shadowbox cuff bracelet. Shadowbox is stamp decorated. Set with green turquoise and one red coral. The coral needs to be oiled. I just rub them with olive oil and the white goes away. 

It measures 1 1/4". The inside measurement is 5 3/8" plus the opening 1 3/8". No hallmarks. Beautiful patina.
