They used machinery to mass-produce jewelry, which was a departure from completely handmade pieces, though often employed Native American artists. This petite point turquoise ring is hallmarked with their logo and Sterling. This weighs 4.7 grams of sterling and blue/green turquoise. Professionally buffed and cleaned. Previously worn from a smoke free home.
