This rare and substantial Victorian hinged locket is an exquisite example of 19th-century British craftsmanship, made in 1871 by jeweller Charles Sanders. Crafted from 9K gold and weighing a notable 11.5 grams, the locket features deeply engraved floral motifs on both sides, showcasing the decorative style associated with the Aesthetic Movement, which prized artistry and beauty in every detail.

A unique feature of this locket is the British Diamond Registration Mark engraved faintly on the bail. Introduced in 1842, these marks served as a safeguard against imitation, recording the rightful owner of the design. The numbers in the registry lozenge indicate this locket was patented on 14 August 1871. Only two locket designs were filed on that day, both registered by Charles Sanders, making this piece not only a work of art but a true collector's item with documented provenance.

The locket opens to reveal a hidden compartment, a clever and patented design element, adding a layer of functionality to its beauty. Its dimensions of 3.5cm (4.5cm with the bail) by 2.8cm by 0.7cm provide a large size for a Victorian locket, making it perfect for carrying a meaningful memento.

In exceptional condition, the locket shows no dents or signs of damage, and the hinge mechanism operates smoothly. Crafted in 9K gold, this locket combines historical significance, patented design, and aesthetic appeal in one remarkable piece.
