How do I care for my ring?

Clean your piece gently using warm soapy water and a soft brush, avoiding harsh chemical dips that can harm softer stones like opal or emerald. Store the ring separately in a fabric-lined box to prevent scratching against other jewellery. Regularly check the security of the claws holding the central cabochon and the surrounding diamonds, especially given the age of the setting. Professional inspection every few years ensures the platinum or gold work remains sound.

Can these rings be resized?

Many platinum and gold rings from this era can be carefully adjusted by a skilled jeweler experienced in antique pieces. The geometric shoulders and intricate gallery work require delicate handling to preserve the original design. Consult a specialist who can determine if the band thickness and side engraving allow for alteration without compromising the structural integrity of the mount.

What is the difference between a sapphire and a ruby cabochon?

Both gemstones belong to the corundum mineral family and share identical hardness, but trace elements create distinct colours. Chromium produces the rich red tones of a ruby, while iron and titanium yield blue sapphire varieties. In these listings, both stones are shaped into smooth domes to showcase their depth of colour rather than relying on facets to reflect light.

How can I tell the period of the ring?

Examination of the metal type, mounting style, and gemstone cut offers clear clues to the era of manufacture. Platinum mountings, geometric frameworks, and old cut diamonds point directly to the 1920s and 1930s. Hallmarks stamped inside the band provide official dates or standard metal purities, while construction techniques distinguish genuine period work from later reproductions.
