Featured is a pre-1948 Beto sterling ribbon clamper. Versions of this sterling ribbon cuff were created by many Taxco silversmiths, all slightly different in subtle ways. 
This one is by Beto, is very well made and reminiscent of the Margot de Taxco version of the bracelet.
It's in excellent condition, a few very minor surface scratches and all the balls are intact with no dings or dents, which is unusual. A very clean piece.
Closes with a very secure, tight and rust free hinge. Nice weight and easy to wear.
Width: 1.75" tapering to 1.25"
Inside measurement: 7" Will fit up to 7" wrist.
Weight: 89 grams
Hallmark: Beto, 925, Sterling, Hecho en Mexico
