FAQs

Edwardian jewellery, spanning the early 20th century, is characterised by delicate platinum settings, intricate filigree work, and a predominant use of diamonds and pearls often contrasted with onyx or coloured gemstones.

Jewellery from this era frequently combined yellow gold bands with platinum-topped mountings to enhance the brilliance of diamonds, alongside contrasting dark stones like black onyx or enamel.

Authentic pieces feature hand-cut old European or old mine cut diamonds with distinct facets, hand-wrought millegrain detailing, and often hallmarks or makers marks indicative of early 20th-century craftsmanship.

An antique ring makes a striking statement piece when worn alone on the hand, or it can be paired with contemporary minimalist bands to create an eclectic mix of old and new.

Care involves gentle cleaning with warm soapy water and a soft brush, avoiding harsh chemical ultrasonic cleaners, and having the setting checked periodically by a professional jeweller to secure old-cut stones.
