Ring (mex 925 stamp) OI4398

Men's ring it is stamped inside says mex 925, other than that I do not know much more about it. I would say this ring is about an 8 in men but I cannot tell the exact size, there are also Knicks on either side of the pattern on the front( example of one side in the last picture). I am selling this cheap just because I do not know much about it( I bought an old jewelry box at a yard sale and it was there) fast reliable shipper. Thanks for looking.
