Rings will range from small to large - all are random - we do not search through any of them. There is the possibility that some of the rings may be from Medieval or Byzantine times. The Roman soldiers wore the rings when they went off to war - often times never coming back.  Thousands of years later, these rings are dug from the earth by modern day treasure hunters in both Europe and the Middle East. As more and more of these rings are removed from the ground year after year, they become scarcer and harder to find.
