FAQs

Rings from the transition period around 1915 frequently pair vibrant central coloured gemstones with light-reflecting diamond halos. Craftsmanship of this era favoured fine platinum or gold settings, geometric symmetry, and delicate millgrain border detailing.

Jewellers during this period commonly employed platinum for setting diamonds due to its strength and neutral colour, alongside 18-carat yellow gold for the band. Central stones featured natural gemstones such as Ceylon sapphires, framed by hand-cut diamonds.

Authentic pieces generally show hand-cut diamonds, subtle hand-engraved or pierced gallery details, and natural colour variations typical of untreated Ceylon sapphires. Gemmological testing can confirm stone origin and period metal fineness.

An antique sapphire ring serves as a focal statement piece suitable for pairing with tailored evening wear or contemporary minimalist outfits. The classic blue and white gemstone combination complements both warm and cool metals.

Clean gently using warm water, mild soap, and a soft-bristled brush to remove dust from behind the claw settings. Avoid ultrasonic cleaners and harsh chemicals to protect delicate vintage metalwork and gemstone mountings.
