This bolo tie uses a sterling silver setting of Kingman turquoise. Kingman turquoise come from the Kingman mine in Kingman, Arizona. The turquoise is stabilized and backed. The bolo tie is made from braided and dyed cow leather. The slide is nickel plated copper. The tips are nickel plated nickel silver. The tie length is 38 inches. The model is my cat, because Mr. Karlsson could not be bribed to put on a dress shirt again.
