Looks like a native (Aztec, Inca?) harvesting corn.
Could be Mexican or South American.
Any inside marks?

Thank you for this info. There are marks inside the shoulders, 925 on one side and on the other what appear to be 3 figures that may be hallmarks but are not clear, the largest could be "A"

If you have the time to do this, here is a list of jewelers' makers mark including antiques. You could look at each one. May take a loooong time to maybe find the one on the inside of this ring.
