How do I wear a brooch?

A geometric diamond brooch can be fastened to the lapel of a coat, pinned at the neckline of a dress, or secured to a scarf. The weight of the piece dictates the fabric needed for support. Heavier platinum and diamond examples require sturdier wools or structured silk, whilst lighter bar brooches sit comfortably on finer textiles.

What is an Art Deco brooch?

An Art Deco brooch originates from the period between the First and Second World Wars, defined by symmetry, clean angles, and stark contrasts. These designs shun floral Victorian motifs in favour of triangles, chevrons, and rectangular structures. Diamonds paired with platinum and black onyx typify this distinct modernist aesthetic.

How do I care for antique jewellery?

Gentle maintenance preserves the integrity of delicate metalwork and securely set stones. Clean platinum and gold settings using warm soapy water and a soft brush, avoiding harsh chemical dips that damage softer stones like emerald or onyx. Store each piece separately in a lined box to prevent scratching.
