Vintage Navajo sterling silver shadowbox bracelet. The shadowbox is inlaid with shiprock mosaic in turquoise and coral. It is set with a row of turquoise and coral. The inside of the shadowbox has patina that is a bit uneven. The back side has been scribble on with an electric engraver. I have no idea why. It is not signed. This style has been done by Tommy SInger and several other Navajo artists. 

The interior measures 6 1/4" plus the opening of 1 3/8". It is for a 7 1/2" wrist and cannot be adjusted in size. It is 1 15/16" wide. Weight: 92.1 grams.
