This is a Navajo/ Zuni Thunderbird multi-stone bolo tie. The bolo measures 1" x 1.5". It is believed to be Sterling Silver, but is not marked or tested. It has decorative stamping around the perimeter, surrounding a Thunderbird rendered in multiple stones: Turquoise, Jet, Red Coral, Mother of Pearl, and Spiny Oyster. It is on a braided black leather strap with copper tips. The bolo is signed on the back, but could not be matched to a particular artist. The tie is in very good condition, with tightly set stones.
