1920s Dress Clip, Green Faceted "Stones", Faux Seed Pearls, Dangling Charm

In phenomenal condition, this lovely dress clip has charm, and has a charm! All "stones" and "pearls" are present and accounted for. Hinged clip is in terrific working condition. I believe this piece is from the late 1920s, somewhere between the symmetry of Deco and the free-flow of Nouveau styles. Content is unknown to me, but only the joining at the hinge reacts to a magnet. Clip has stamped marking "ATJ80112" in two places, which seems to refer to the hinge clip and not the piece itself. Approx 3.75" x 1.5"
