Native American Pendant Silver Turquoise Navajo Silversmith David Umpleby

I am selling a beautiful sterling silver and turquoise pendant handcrafted and signed by well-known Native American Silversmith David Umpleby. Vintage 1980s. The weight is an impressive 55 grams and 3" high (including the bale) and 1.5" wide. On the back is etched: Sterling made in Santa Fe DEU". The DEU are the initials for David Umpleby. I am only selling to buyers within the United States. The selling price is $175. The price for this piece in a Southwestern jewelry store would be approx. $325.
