Very pretty Edwardian? locket, 11/16" x 13/16" in size and in very good condition.  The top of the front panel is marked: "9 CT BACK & FRONT".  It is also engraved in elaborate script with what I believe are the initials RG.  The back of the locket is plain, and there is one photo bezel on the inside back panel.  The other side is lined with some very old paper.  The photo appears to be newer than the locket itself.
