So we are not listing as anything other than a silver metal bracelet because all that is marked is TAXCO MEXICO. We tend to think it?s likely that it was marked 925 or sterling and perhaps worn off or just rubbed off over time. Usually if it?s not sterling it would say ?Alpaca? which is mixed metal that is completely not silver. Bottom line is we have no idea what it is made of. But it?s cool enough that someone is going to want it regardless of the metal content. See the photos and grab it if you like it. We only have one. And when it?s gone, it?s gone! Will ship USPS with tracking to winning buyer
