From what I can find, Alpaca silver is not sterling silver.

Post a clear picture of the hallmark, and maybe we can decipher it.

Thanks Emerald...I had read that article before, so thats how I knew about Alpaca, but the 925 threw me off. I posted 2 pics so you can that both are on same item!

Is the bracelet one of those stone inlayed cuff ones? If so they are not 925 and do not always carry the Alpaca mark.

The 925 was added after the bracelet was made when it was stamped Alpaca. This type are common and were factory made in Mexico by the thousands and can be picked up in S. Ca at swap meets. for a dollar or two. 925 stamps are easily purchased and someone somewhere was trying to make a dishonest buck. Could have been done by a supplier to a street vender in Mexico or could have been done in the US.

 Mexico is very strict about their sterling silver and how it is marked. If hand fabricated it will have th first letter of the town were it is made i.e T for Taxco followed by the first letter of the smith's surname. Then there is a dash followed by the number assigned to that smith based on the number of smiths who have that letter.

Going along with what Lenorep posted, the above link explains about Mexican silver.

And yes the hallmark to me does appear to say Alpaca.

I'll speak in general and not about this particular bracelet. Alpacca (I think with double c) also known as Nickel silver or new silver or German silver is a copper alloy with nickel and zinc. An alpacca jewel looks like silver but it contains no silver at all. I have some forks marked with the stamp :nickel silver , but as I've said above they are not real silver, they are alpacca.

Mexican Silver is actual silver from Mexico, not another name for Alpaca.

I see the 2 C's used when it's from Italy, or that area, but Mexico, at least, only uses 1 C.

There are 1000's of falsely marked bracelets from Mexico.  Looks like several the OP bought are of the kind usually faked.  They often have a silver plating so fool simple tests.

Well my seller took her item back graciously. She truely seemed to not know that Alpaca is fake. I did a search for sterling silver Alpaca, and there seems to be other sellers that do not know either!

LOL!
