This vintage Mexican sterling silver ring is what is known as a poison ring! It actually opens to reveal a small compartment that the wearer could put snuff in, but it is much more fun to picture some secret nefarious activity! This ring is quite structural and three dimensional in design. It is hard to describe all of the decorative features in this ring. There are layers of cut out elements and added silver balls as well as incised lines. The ring is a piece of art!
The marks inside the ring reveal that is was fabricated in Taxco, Mexico, a well known artisan community for silversmiths. It is stamped "925" so it is sterling silver. It also bears a the initials "EJD" an artist who is listed as working from c. 1948-1979, although there is no name associated with the listing.
The ring weighs 9.2 grams. The face is approximately 22 mm (7/8 inch) in length and has an adjustable band that is 8 mm (5/16 inch) wide.
