FAQs

Art Deco jewellery is characterised by geometric precision, symmetrical designs, and a strong emphasis on clean lines, frequently contrasting precious platinum with vibrant gemstones like sapphires, rubies, and emeralds.

Cluster rings from this era predominantly utilised platinum or white gold settings to maximise the brilliance of old-cut diamonds surrounding a central coloured gemstone such as a Ceylon sapphire.

Authentic pieces typically exhibit period-specific stone cuts such as old European or cushion cuts, hand-crafted millegrain detailing, and authentic makers marks or purity hallmarks appropriate to the 1920s and 1930s.

An antique cluster ring serves as a striking standalone statement piece that pairs effortlessly with minimalist contemporary attire, allowing the historic craftsmanship and vibrant gemstone colour to take centre stage.

Preserve antique jewellery by storing pieces individually in soft pouches, avoiding harsh chemical ultrasonic cleaners, and having professional settings and prong integrity inspected annually by a certified specialist.
