Silver Bangles from Mexico

2.5 inch diameter. Fits average adult wrist. Bought in Mexico in the 1970’s. They came as a set of three bangles but each is also pretty worn alone. They are all stamped Mexico. One is also stamped 925. I do not know the silver content but they all polish easily with silver polish. Designs are pressed into the silver. This is a beautiful set if you love silver!!!!
