Vintage 925 sterling silver Navajo Southwestern ring with turquoise and coral

Gorgeous and very old handmade sterling silver Navajo ring. With very good quality blue turquoise and red coral. This type of turquoise is very expensive and no longer available (as it has been all mined). Old Pawn jewelry, from around 1920th. Size 6. In excellent condition for it's age. Not stamped (typical for Native jewelry prior to 1950th). Has old vintage patina, which is valued by collectors and is part of the style and charm of any antique Southwestern jewelry. Removing it will reduce the value of this ring.
