Vintage Navajo Sterling Silver & black braided leather bolo tie. The rosette slide is sterling silver and set with 25 natural turquoise stones. It has a diameter of 1 1/4". Very tarnished. It is mounted to a brass tie clamp that has some silver plate on it. The bolo tips are cast brass. I have not seen this before. They are usually sterling too. The leather is in great condition and measures 34 end to end. No hallamks.
