Awesome Navajo vintage ring.  Inset with a oblong brown and black agate (which does have a stablized crack across the center).  Sawtooth bezel.  The front of ring measures 1 3/4″ long and has very nice silver tooling around the bezel.  I call the silver dots “raindrops”.  Size is: 5.5.  Signed “JB”.  Tested silver.
