This is a wonderful cuff bracelet made of Mexican sterling silver that is set with a single Onyx stone.  The bracelet is made in a “modernist” style, nice clean lines and very modern looking - it could pass for a contemporary piece, although I believe that it dates to the 1980s.  The interior is stamped “Mexico TS-70 925”.  According to the Little Book of Mexican Silver Trade and Hallmarks, TS-70 was used by the Two Trees studio of Taxco.  The interior opening of the cuff measures 2 3/8” by 1 3/4” and the front of the cuff has a height of 1 5/8” at the onyx setting.  It weighs 28 grams (1 ounce).  It is in very good condition with no pronounced wear.

This is a wonderful example of Mexican modernist silver jewelry - sure to be noticed!
