Onyx & Paste Belt Buckle with Matching Button | British Art Deco | c.1930s

This striking Art Deco belt buckle and matching button set combines deep, polished black onyx with brilliant-cut paste stones - a bold contrast typical of 1930s glamour.

Likely British in origin, the buckle spans 10cm in width by 3cm in height, while the square button measures 3cm across.

Set in a clean, modernist design, both pieces reflect the Deco fascination with geometry, symmetry, and high visual impact using accessible materials.

Paste - finely cut glass designed to imitate diamonds - was especially popular in this era, allowing women to wear sparkle and sophistication without the price tag of precious stones.

Paired with onyx, it became a signature look: sleek, confident, and distinctly modern.

This buckle would likely have adorned a wide satin belt or structured evening dress, worn high on the waist, ideal for cocktail parties, cinema nights, or dance halls.

The matching button would have been worn on the same outfit, sewn onto a coordinating jacket, cape, or even a handbag.

Elegant, sculptural, and enduring in its style, this set remains a sharp example of Art Deco design and wearable now as it was then.

Available exclusively at ELTONS, Grays Antique Market, Mayfair, London.
