FAQs

Edwardian jewellery, produced during the reign of King Edward VII from 1901 to 1910, is characterised by light, airy designs, extensive use of diamonds and pearls, and the introduction of platinum-topped gold settings to enhance the sparkle of gemstones.

Craftsmen of this era frequently utilised 18-carat yellow gold for structural integrity, paired with platinum settings on the face of the piece to securely hold diamonds while maintaining a bright, white finish that contrasted with the yellow gold backing.

Authentic pieces often feature old-cut diamonds, hand-fabricated metalwork with delicate millegrain detailing, and hallmarks specific to early 20th-century British or European assay offices.

Antique brooches offer versatile styling options and can be worn pinned to lapels, securing silk scarves, fastened at the neckline of a blouse, or repurposed as a pendant on a modern chain.

To preserve these pieces, store them individually in soft-lined boxes to prevent scratching, avoid harsh ultrasonic cleaners if the piece contains foil-backed stones or natural pearls, and have the settings inspected periodically by a professional jeweller.
