Signed sterling silver leather bolo tie. This is Navajo and signed by Stu Y. (May be a member of the Yazzie Family.) 

The oval concho slide is deeply stamp decorated and a raised center. It is set with a deep blue turquoise stone that has dark matrix. It measures 2 1/2" by 2 1/4" wide. The tips are sterling as well and measure 2" long. The hardware that holds the slide in place does not snap down super tight, but the slide does stay in place. 

Tie is black braided leather. Measures 38" long.
