This is a wonderful vintage Native American sterling silver petrified wood pin. This pin features a beautiful bezel-set piece of gray, black, and burnt orange petrified wood surrounded by nice silver work. The metal acid tests for sterling silver. The back is unmarked so the Native American tribe and silversmith are unknown. The piece measures 2 inches wide by 1 5/8 inches high. The pin measures 1 3/4 inches long. The piece weighs .83 ounces or 23.6 grams. Add this lovely vintage pin to your collection!
