Makers Mark

Question

A little stumped on this one? I am seeing some listing saying this is Sterling from Mexico. I know I was in Mexico in the very early 80s with my mom, I was a kid so I don't have a clue what she bought as far as jewelry. Any assistance appreciated, I doubt it is sterling and I don't have a clue about the stones.

The mark you show is not a typical Mexico mark, and there usually is always Mexico as part of the marks somewhere. The 'stones' look like resin  or maybe enamel, not typical enamel but then I am hardly an expert, if they are actual stones, then my first guess would be carnelian. It's a bit tough to tell from the pics.Did you polish this piece since the '80's , did it tarnish at all over the years ? Looking at the mark again it reads to me as 757 which stands for 75.7% a common silver alloy...
