Navajo Sterling Silver Coral Ring Old Pawn Size 5

Wow! This beauty is a vintage Navajo sterling silver and coral ring. The stone is a pinky/salmon color elongated oval, surrounded by a leaf motif design in sterling silver. There are no identifying markings inside the ring. It is heavily patina'd and I think this adds to the beauty. But please feel free to polish it if you prefer your silver shiny. Size 5. The face measures approximately 1" x 5/8" No issues.
