These just struck me as a very beautiful pair, one ring fitting inside the other, neither quite round, the larger one a bit fatter than the smaller. Nice objects for the desk or table, useful as paperweights, satisfying to hold, and just lovely.
Larger measures 4 11/16" across, 7/16" thick. Smaller 3" across and 5/16" thick. Hand-forged, with lots of years on them, with nice surface variation as a result. Sold as a pair.
