A friend found this on a cave tour a long time ago. The flash light from her kid hit it of the side and it sparkled back at them. Maybe it was meant for someone with big knuckles? I'm thinking 20s 30s? No mark on it. Has anyone seen a ring like this?
usually made for people with large knuckles/arthritis swelling. Not sure its that old. Could be I guess ? I am thinking that it is likely pretty modern, like within the past 40 years.
