Old Blue Lander Dead Pawn Sterling Silver Ring 925

Thank you for looking at this amazing find. I found this treasure here in the Southwest recently . This is a traditional Native American motif and design, probably Navajo. The ring is not stamped but tested as solid sterling silver. The gemstone, old blue Lander is some of the rarest turquoise in the world. 8.1 grams 2.5 x 3 cm is the façade of the ring Size 5
