It was listed by Corvidae Antique. Sold pieces stay on Sellingantiques as a record of what has passed through, and the next one is rarely far away.
Corvidae Antique has dated this piece to the Victorian era.

The piece is in very good antique condition though would probably benefit from a gentle clean; there is a minor crease to the surface on the back, but it doesn't show up in the photos. The bail and hinge are in good working order and the clasp snaps securely shut with a click.
Size: 2.5cm long. 1.9 x 1.8cm, not including the bail.
