Vintage 925 handmade Southwestern / Western Mexican bracelet

Vintage handmade bracelet. Likely from the 50th or older. Stamped 925 and Hecho en Mexico. Fits sizes S and M as it can be bent to enlarge the opening on the back. It has a small spot on one side, and the 925 stamp is partially visible on the front (as shown in the last two pictures). Not sure if it is actually made of sterling silver (due to that spot), so selling as is and pricing competitively.
