FAQs

Art Deco jewellery, popularised during the 1920s and 1930s, is characterised by geometric shapes, clean symmetrical lines, openwork metal filigree, and the prominent use of platinum alongside diamonds and coloured gemstones.

Brooches from the 1920s were frequently fabricated using platinum or white gold to allow for intricate, strong openwork settings, often decorated with fine milgrain edging and pave-set diamonds.

Authentic pieces generally feature metal purity stamps, fine hand-applied milgrain detailing along metal borders, geometric symmetry, and period-appropriate gem cuts such as old European or single cut diamonds.

An antique bar brooch can be attached to a coat lapel, secured to a scarf or hat band, worn at the collar of a button-down shirt, or pinned to a fabric ribbon worn as a neck choker.

Clean platinum and diamond jewellery using a soft-bristled brush with warm water and mild liquid soap, avoiding harsh chemicals, and store pieces individually to prevent surface scratching.
