FAQs

Edwardian jewellery, spanning the reign of King Edward VII from 1901 to 1910, is characterised by light, airy, and feminine designs often utilising platinum and yellow gold settings, frequently incorporating diamonds and sapphires in lace-like motifs.

Traditional construction often paired an 18-carat yellow gold shank with platinum-topped bezels and claws to enhance the brilliance of old-cut diamonds against a central gemstone.

Authentic pieces exhibit hand-cut gemstones such as old mine or old European cuts, hand-beaded millegrain edge detailing, and often feature subtle maker marks or traditional British hallmarks.

An antique cluster ring pairs effortlessly with contemporary minimalist outfits to create a striking contrast, or can be stacked alongside modern bands for a curated mixed-era aesthetic.

Preservation involves regular professional inspection of the claw settings to ensure stones remain secure, combined with gentle cleaning using warm soapy water and a soft brush, avoiding harsh ultrasonic cleaners.
