What is a platinum diamond pin used for?

These pieces function primarily as decorative fasteners for lapels, scarves, hats, and heavy fabrics. Historically, they secured specialised garments and cravats while signalling social status through precious materials. Today, collectors wear them as versatile brooches or adapt them into pendants using hidden loops. They remain practical accessories that add historic character to modern attire.

How can I tell an Art Deco pin from an Edwardian one?

Art Deco pieces rely on strict geometry, symmetrical layouts, and sharp contrasts involving black onyx or calibre-cut rubies alongside diamonds. Platinum dominates these linear compositions. Edwardian items favour softer floral motifs, garlands, bows, and natural pearls set against delicate white metal lace work. The overall aesthetic feels lighter and more fluid than the later Deco style.

Why is platinum used instead of gold in these pins?

Platinum possesses exceptional strength and density, allowing jewellers to fashion ultra-thin claws and intricate wirework without risking stone loss. This durability made it the preferred metal for securing dense pavé diamond fields. Its naturally bright white colour also does not tarnish and complements the icy sparkle of old cut diamonds perfectly.

Can these pins be worn every day?

Most antique platinum pins withstand regular wear provided the pin stem, hinge, and safety clasp remain secure. The inherent toughness of platinum protects the structural integrity of the delicate settings. Owners should handle pieces with delicate openwork or natural pearls with care to avoid bending the fine metal bridges during fastening.
