Vintage Mexico Sterling Silver Green Onyx Masks Bracelet

This fantastic bracelet is most likely from the 1970s and was made in Mexico. Stamped on the back of the clasp, HECHO EN MEXICO (with part of it not fully stamped).

Gorgeous green onyx carved into masks, each one set in a fancy filigree and ball sterling frame. Two matching rings are also for sale here on this site. Measures 7" long, and 1-1/4" wide. From a high end estate.
