This is not your typical 1920's Fred Harvey piece. It is completely hand made and fabricated ( all the silver was cast by hand and formed into shape ) It looks like even the pin back was made by hand! This piece was made by one of the greats, Mark Chee, Fred Peshlakai, Morris Robinson, all made similar pieces.
About 2 7/8" long by 13/16" wide. The Gem grade turquoise is Nevada mine, and most likely from Red Mountain, Indian Mountain, Pilot Mountain or similar. Stone is about 5/8" by 7/16" at the widest. The stone is worth $150 or so by itself! A highly collectable piece!
