The Sustainable Choice

Antiques are the ultimate green purchase. By choosing historical pieces over newly manufactured goods, you completely eliminate the carbon footprint of modern mass production while preserving exceptional, timeless craftsmanship.

FAQs

Jewellery from the 1930s often bridges classic Art Deco geometric precision with emerging Retro fluid curves. Pieces frequently featured platinum mountings densely set with mixed diamond cuts, such as baguette, brilliant, and single cuts, creating textured floral spray and ribbon designs.

Platinum was the predominant precious metal used for high-end mountings due to its strength and bright white lustre, which enhanced the fire of diamonds. Fine diamonds remained the primary gemstone, often arranged in pave and channel settings.

Authentic pieces usually display period-appropriate stone cuts, hand-finished settings, and historical purity marks or makers marks. Testing the metal composition with acid or XRF technology confirms platinum content, while pin mechanisms like rollover safety clasps or double clips reflect era-specific manufacturing.

A classic diamond pin can be fastened to coat lapels, modern tailored blazers, or silk scarves for formal wear. Alternatively, securing the brooch at the waistline of a dress or on the band of a hat offers a refined contemporary accent.

Clean gently using lukewarm water, mild soap, and a soft-bristled brush to remove dust from behind the settings. Avoid harsh ultrasonic cleaners if stones are delicate, and store the item in a fabric-lined box separately from other jewellery to prevent scratching.
