Looks like Sterling to me, so WHAT is Alpaca??
Many Bracelets, brooches and pretty things from Mexico and South America look a lot like Sterling, and some are even actually marked Sterling, but they are not. They are made from a metal called "Alpaca". So what IS Alpaca? Alpaca is an alternative silver metal made from approx 60% copper, 20% nickel, and 20% Zinc. There is no silver in Alpaca at all! Keep that in mind as people will try to sell it to you as a lower grade of silver, when it's not silver at all. We've had some pretty amazing brooches and bracelets cross our desk at "The Discerning Blonde VCJ on Etsy" and one would never know that these weren't a grade of silver except that there isn't the standard Sterling Silver tarnish that usually accompanies such pieces. Alpaca is also used in table and flatware. So remember, some things from Mexico and South America are not as they seem. Test your South American and Mexican Silver and be sure that it's real....
