This American Indian ring is an ornate sterling silver and black Onyx design. The craftsmanship of this ring is exceptional.  I purchased the ring somewhere in the desert southwest in my travels in the late 1970s. 
 

     
 
The ring is Navajo and is signed by the artist with just a capital letter S, and it is stamped Sterling. This is a very long ring has tear drop Onyx cabs and ornate medallions at center and feathers top and bottom. The ring shank is a three prong design and is hand hammered. 
 

     
 
 The ring is a fixed size 7. From top to bottom the ring is 1 3/8" or 35 mm long.  The entire ring is in pristine clean like new condition with no imperfections or flaws. There are no scratches, scuffs, or signs of wear.
