FREE: Size 7 ANTIQUE RING STAMPED K in a circle

The listing, Size 7 ANTIQUE RING STAMPED K in a circle has ended.

This is a antique ring one of a kind. 1 stone is missing but you can hardly tell. I have no idea what the stones are. Upon investigating the stamp I came across what the stamp may mean. My fiancee's grandma was a ring collector and this is one of her rings from her collection. It is old but in good condition except that one stone missing. I tested with a magnet. It doesn't stick to it at all. It does have a spot on it but it isn't rust or fading. It has a tiny red spot on it but that's it.
***I added some info to what the red spots could be but not sure if that's what the spots are*** Did my best posting all the pics I could and information on it I could try and find. Ty
