How do I identify an Art Deco sapphire ring?

Art Deco sapphire rings display geometric lines, symmetrical patterns, and frequent use of platinum alongside calibration-cut stones. Look for architectural motifs and millegrain detailing around the bezels. These pieces often incorporate old cut diamonds in cluster, target, or navette arrangements, distinguishing them from later curved mid-century designs.

What is an unheated sapphire?

An unheated sapphire is a natural gemstone that has not undergone thermal enhancement to improve its colour or clarity. Natural stones retaining their original earth-formed characteristics are valued by collectors. Laboratory certificates often accompany these gems to confirm their untreated status and geographical origin.

Can I wear a vintage platinum ring daily?

Platinum is a dense and durable metal well-suited to everyday wear, resisting the thinning that softer precious metals experience over decades. The high tensile strength protects antique settings. Regular checks by a jeweller ensure the claws and millegrain remain secure around the centre stone and smaller diamonds.

How should I clean my platinum and sapphire ring?

Clean the ring using warm water, mild washing liquid, and a soft-bristled brush to remove oils from beneath the sapphire setting. Avoid harsh chemical cleaners that might affect older alloys. Periodic professional ultrasonic cleaning and inspection will keep the platinum prongs secure and restore the sparkle of the diamonds.
