This vintage, mid-century modern sterling cuff is the creation of the Taxco artisan, Alfredo Villasana.
This piece features a heavy, wide 2" band of oxidized sterling with a bright sterling lip at the edges and a 2D appliqué 'wave' design. The cuff is in very good condition, slightly out of round, with minor surface scratches and a little wear on the oxidation, but nothing that detracts from this extraordinary piece. I have had it cleaned and it's ready to go!
I have listed many Villasana pieces in my shop but this is the first of this kind of appliqué, MCM style that I would usually attribute to Enrique Ledesma. 
This is unusually  large size for a vintage piece and will fit a 7.75" wrist.
