Incredibly good find ! Looks like it was made from a large coin - can't help you with what denomination though. This could have been made a century ago- or a bit more by a soldier as so called " trench art" . Could we get some story about where you found this ? I really look forward to finding a Silver coin ring someday (I've actually hammered out 3 of these from half dollars - they are a LOT of work !) Get excited about this find !!
