FAQs

Mid Century jewellery encompasses designs from the 1940s to 1960s, often featuring bold gold work, sculptural floral motifs, and traditional cluster settings that highlighted central gemstones.

These rings typically feature natural blue corundum sapphires and old cut diamonds set in a combination of yellow gold for the shank and platinum or white gold for the cluster head to enhance stone brilliance.

Authenticity is identified through hallmarks indicating metal purity, handcrafted settings typical of the era, and the distinct characteristics of old cut diamonds alongside untreated or traditionally treated sapphires.

A vintage sapphire ring serves as a striking focal point and pairs well with both minimalist contemporary attire and evening wear, often complemented by matching gold or platinum accessories.

Preservation requires professional cleaning using ultrasonic techniques only when stone settings are verified secure, alongside routine checks of the claws and storage in a lined jewellery box.
