This very cool ring is made of solid Sterling Silver. It is a signet ring, the face is flat and the carving recessed. It has a strong Native American influence but it is only marked "Sterling" with no maker's mark. It is similar to Mexican Biker rings.
The setting is 21mm north-south. The ring size is 7 US, can be sized. It weighs approximately 13 gram, hefty. Estimated to date from the 1950's.
This vintage signet ring is in excellent condition, the patina is intentional and makes the pattern pop.
