These bracelets are handcrafted from nickel (a very hard, silvery white, lustrous metal, somewhat heavier than iron). Nickel holds its luster and does not tarnish easily.

We have seen these items on some sites claiming they are sterling.  Any sterling items from Mexico will be marked with ".925". Bracelets, like the ones shown here, will be marked "alpaca".
