FAQs

Art Deco jewellery, prominent during the 1920s and 1930s, is characterised by geometric symmetry, clean lines, stylised motifs, and a strong emphasis on contrasting gemstones and precious metals.

Jewellery from this era frequently utilised platinum, white gold, and yellow gold set with vibrant gemstones such as aquamarine, sapphire, emerald, and brilliant-cut diamonds.

Authentic pieces typically exhibit period-appropriate settings, hand-cut gemstones consistent with 1920s lapidary techniques, makers marks, and metal purity hallmarks characteristic of the era.

An antique pendant can be styled as a focal point by pairing it with simple, solid-colour necklines or layered with minimalist modern chains for an eclectic yet sophisticated look.

Clean the piece gently using warm soapy water and a soft brush, avoiding harsh chemical ultrasonic cleaners, and store it separately in a lined jewellery box to prevent scratching.
