Why Sellingantiques dated this piece to THE 1910s:
Platinum facing over yellow gold: fixes the work after 1900 when platinum became standard.
Eight-cut diamonds in scalloped millegrain borders: cutting style that fits early twentieth-century clusters.
Hand-pierced coronet under-gallery: openwork pattern popular before cast mass production.
Slight softening of the gold bezel and shank: decades of regular wear.

This is an independent date report produced by Sellingantiques using its own proprietary system. The process uses the photographs shown on this page. The system is never told the date the dealer has declared. This report shows that the two dates corroborate.

FAQs

Edwardian cluster rings from circa 1900 to 1915 are noted for light-capturing metalwork, often pairing yellow gold shanks with platinum or silver-topped settings to highlight white diamonds around a central coloured gemstone.

Jewellers during this period frequently combined eighteen-carat yellow gold with platinum face settings, securing gemstones with delicate hand-carved claws and incorporating natural rubies and diamond accents.

Authentic pieces exhibit era-appropriate gem cuts, such as oval or cushion mixed-cuts alongside hand-cut diamonds, subtle wear consistent with age, and historical assay marks or makers stamps.

A classic gemstone cluster ring functions as a standalone statement piece or can be stacked with minimalist gold bands to create a textured, contemporary contrast.

Clean gently using warm soapy water and a soft-bristled brush, avoiding ultrasonic cleaners, harsh chemicals, and steam treatments that might compromise historic mountings.
