Vintage Mexican Black Inlay Ring Unisex

Vintage Black Onyx Inlay ring. This is an 80's Mexican piece. It is classic for the time period. There is a hallmark but I cannot read it even with a loupe. Three connected horizontal boxes each with a symbol inside - the middle one looks like it might be a bell. I captured as best as I could - please see pics for best idea of condition and size. Tests as sterling - heavy thick silver plate over another metal judging by the wear - handmade. 7.5/7.75 - please see pic on mandrel. Black Onyx is said to protect from negative energies - It is a wonderful grounding stone. If you like cool old stuff this one fits the bill!
