I've done some significant research for days now on the internet, and just can't find that much information on Joy Mex. Unfortunately when I go to upload two really good photos, it states that the board forum image quota has already been met.
So my ring has a makers mark of JOY MEX PLATA surrounding 925. No eagle anywhere. Not sure of the stone either, but hard to ask a question without showing a photo. Dark green with black....maybe malachite?
