Here is a link to a ring that was attributed to Jane Popovitch. It only has the P on it.

Ring with P Mark

Found this at a pawn shop. The stone appears to be Hemetite. The setting reminds me of pre 1990 SW style jewelry. ’ The strange thing is it looks like the setting was soldered onto the ring shank, if you get what I mean. Have never seen a shank with that oval area before. Does anyone recognize the mark? Thanks [IMG_2945] [IMG_2949] [IMG_2951] [IMG_2954] [IMG_2958]
