Looking into the marks on this silver Bracelet

Trying to find out about this silver piece. I saw a mark on something someone posted here that looked similar

and hoping to find some help identifying the artist.

Hello, have you tested to see if this item is solid silver? I ask because all the Mexican items I’ve seen had 925 hallmark, like in this photo. I thought it was strange that your item in the middle had PCA.

when it is polished its a much brighter sliver ive had it stored a long time. But no i havent tested it yet. Do you have anymore information on mexican sliver? Anything is helpful. I appreciate the response.
