FAQs

Half eternity rings featuring alternating sapphires and diamonds gained significant popularity during the Victorian and Edwardian periods, often symbolising eternal love and loyalty.

These rings typically utilise 18-carat gold, combining copper and silver alloyed with pure gold, set with natural blue sapphires and brilliant-cut or princess-cut diamonds.

Authentic pieces generally feature hallmark stamps indicating metal purity, hand-cut gemstones consistent with period techniques, and signs of genuine age such as minor facet wear.

Vintage gemstone bands provide a sophisticated contrast when stacked with modern minimalist gold bands or worn alone as a subtle statement piece.

Clean these rings gently using warm soapy water and a soft brush, avoiding harsh chemical ultrasonic cleaners, and store them separately to prevent scratching.
