Circa – 1910.

FAQs

Edwardian jewellery, spanning the early 20th century, is characterised by delicate platinum settings, intricate filigree work, and the prominent use of diamonds and sapphires to create light, lace-like motifs.

Goldsmiths of this era frequently utilised platinum, which allowed for finer, stronger settings than silver or gold alone, alongside yellow gold accents, natural unheated sapphires, and old-cut diamonds.

Authentic pieces typically feature hand-cut stones such as old mine or single-cut diamonds, hand-forged platinum settings with millegrain edging, and period hallmarks corresponding to the country of origin.

An antique ring acts as a focal accessory; pair it with minimalist contemporary attire to let the historic craftsmanship stand out, or display it in a velvet-lined vintage ring box on a dressing table.

Store antique rings separately in soft pouches to prevent scratching, avoid ultrasonic cleaners due to potential weakness in historical settings, and have the prongs checked periodically by a professional jeweller.
