FAQs

Edwardian jewellery, produced between 1901 and 1910, is characterised by delicate platinum settings, lace-like filigree work, and the prominent use of diamonds and sapphires.

Jewellery from this period frequently combined newly workable platinum with yellow gold, often featuring old-cut diamonds and natural unheated gemstones.

Authentic pieces typically feature hand-carved details, old European or single-cut diamonds, genuine hallmarks denoting 18ct gold and platinum, and traditional millegrain edges.

Antique rings can be worn as standalone statement pieces, paired with contemporary minimalist bands for contrast, or incorporated into curated ring stacks.

Star sapphires should be cleaned using warm soapy water and a soft brush, avoiding harsh chemical dips or ultrasonic cleaners to protect the cabochon stone and precious metals.
