Vintage Navajo Large Eagle Thunderbird Royston Turquoise Bolo Tie

Amazing and very unique, vintage Navajo large eagle bolo tie piece with a nice Royston turquiose (green with brown carmel matrix) freeform cabochon. The eagle could be considered a Thunderbird since it was created by a Native American crafts person. This piece came from a very large lifetime estate collection of Native American jewelry. Condition: Nice vintage condition! Lightly cleaned with much of the original patina has been left to retain the value of the piece. Hallmarks: The artist signed the piece, but it is very hard to read. Tested and confirmed as sterling. Measurements: 2 5/8" Long x 2 3/4" Wide Weight: 69.1 grams
