When I first purchased this I was told it was a Medieval Ring but due to the stone being faceted I would say when this was made to be the end of the Medieval period which would be this ring is approximately 500 to 600 years old. The metal band is not attracted to a magnet and looks to me to be copper. I did not clean it to see. If you look close, it would look like the part of the copper where the stone fits in is cracked but I believe it was made that way and the copper was wrapped around the stone and the two copper ends are locked in place(see one of the pictures). The metal band looks like it was hammered when it was being made.
