Lovely smaller locket in a unique shape with ornate details.  Has engravings at top and a blank cartouche that could be engraved (by jeweler).  Measures just over 1 inch (with larger bail) x 0.5 inches.  Two frames inside with old photos.  Inside could use a good cleaning.  Closes with a snap.  Faded markings on. bail but too hard to make out.  Likely gold filled.
