How do I identify an Art Deco platinum diamond sapphire ring?

Look for sharp geometric lines, symmetrical target or navette motifs, and fine millegrain borders characteristic of the 1920s and 1930s. These pieces typically pair heavy platinum top settings with bright white or yellow gold shanks, often utilising calibré-cut sapphires.

Are unheated sapphires common in vintage rings?

Unheated sapphires appear regularly in period pieces from origins such as Burma, Ceylon, and Kashmir, possessing natural colour stability. Certification from gemological laboratories often accompanies these stones to confirm the absence of thermal enhancement.

Can I wear a vintage sapphire ring every day?

Sapphires score nine on the Mohs hardness scale, making them exceptionally durable for daily wear when set securely in platinum. Prongs and millegrain edges on antique rings should be checked periodically by a jeweller to ensure stones remain firmly seated.

What is the difference between a cluster and a target ring?

A cluster ring groups diamonds and sapphires in a floral or general clustered arrangement around a central focal stone. A target ring specifically uses distinct concentric bands of contrasting gemstones to create a bullseye visual effect.
