A vintage platinum diamond brooch represents an intricate wearable jewel designed to fasten garments, featuring central gemstones set within dense white metal frameworks.
The pieces appearing on this page span the Edwardian, Art Deco, and mid-century periods, showcasing forms from simple bar pins to elaborate double-clip pendants.
Art Deco geometric designs dominate the selection, often pairing bright diamonds with contrasting onyx, rubies, or sapphires in symmetric arrangements.
How they were made

The Vintage Platinum Diamond Brooch Glossary
- Millegrain
- A decorative technique involving a row of tiny raised metal beads along the edge of a setting. It softens the metal profile and adds texture.
- Bar brooch

- Double clip brooch
- A versatile ornament comprising two matching clips joined by a removable frame. Wearers could separate them to use as dress clips.
- Old cut
- A diamond facet style pre-dating modern brilliant cutting, characterised by a smaller table and high crown. These stones produce a characteristic warm candlelit sparkle.

Vintage Platinum Diamond Brooch: Frequently Asked Questions
How do I wear a vintage brooch safely?
Pin the brooch through sturdy fabrics like wool or tweed, ensuring the pin tongue fastens securely into the safety clasp.
For delicate silks or lighter garments, use a backing disc or anchor the pin through an inner layer to distribute weight evenly.
Can a brooch convert into a pendant?
Certain designs feature hidden hinged loops or detachable bails on the reverse side. This allows the wearer to slide a chain through and transform the garment ornament into a neckpiece.
Inspect the back of the mounting for folding loops before attempting conversion.
How do I date an Art Deco brooch?
Examine the geometric symmetry, straight lines, and combination of platinum with contrasting stones like onyx or calibré-cut rubies. These traits point towards the interwar period of the 1920s and 1930s.
Maker marks and box fittings also assist in narrowing the production decade.
What is platinum-topped gold?
Platinum-topped gold refers to an older construction method where a sheet of platinum is fused to a gold backing. This technique emerged before platinum could be easily worked on its own.
It offers the white appearance of platinum on the front while utilising gold underneath.
