I think you are asking if there is anything stamped onto earring or ring? If so, I don't see any stamps on earrings, there is something sramped on inside of ring, but its way too small for me to read. Maybe it's the brand or something? I'll try to find a magnifying glass. There is also a vertical line oppsite from where stone is, but not sure what that means. Maybe it was resized at some point.
