Engraved Dainty Flower Locket - Gold Filled - Antique - As Found

This special well loved treasure has engraving on the front of a flower pattern.  Locket has wear.  Front is semi indented (see photos) and back has some bite marks (probably worn by a child).  Both glass frames present but the glass is almost opaque so can’t see what’s behind it.  Locket circa early 1900s so likely had a rich history.  Locket measures approx 20mm (with top loop) x 8mm.  Unmarked but likely gold filled.
