Vintage Mexican Fire Agate Ring.  These stones are rare & vintage fire agate jewelry is hard to find.  This 1960's ring features a beautiful stone & was made by a Navajo artist.  There is no stamping inside the ring (which is common for that era), but it tested sterling.  

***Vintage jewelry sold on this site is as-is... and will include the natural patina/oxidation that comes appears over time with vintage jewelry. The value is greater when the patina is present,  so we in no way want to affect the character/authenticity of the piece.
