FAQs

Art Deco jewellery, prominent during the 1920s and 1930s, is characterised by geometric precision, stylised motifs, and a strong architectural influence, often contrasting polished precious metals with brilliant gemstones.

Pieces from this era typically feature high-purity yellow gold or platinum settings, frequently showcasing hand-cut diamonds such as old European cuts or old mine cuts alongside calibrated precious coloured gemstones.

Authentic pieces exhibit hand-crafted hallmarks, signs of genuine age such as minor surface wear on the metal, and hand-cut stones with slightly irregular facets characteristic of pre-laser cutting technology.

An antique ring serves as a focal statement piece that pairs well with minimalist contemporary clothing or can be stacked alongside sleek modern bands for an eclectic, textured look.

Store antique pieces individually in soft-lined boxes to prevent scratching, and clean them gently using warm soapy water and a soft brush, avoiding harsh ultrasonic cleaners which can compromise old settings.
