Antiques are the ultimate green purchase. By choosing historical pieces over newly manufactured goods, you completely eliminate the carbon footprint of modern mass production while preserving exceptional, timeless craftsmanship.

Art Deco jewellery, prominent during the 1920s and 1930s, is characterised by geometric symmetry, bold color contrasts, and clean architectural lines. Pieces frequently feature step-cut gemstones, millegrain detailing, and combinations of diamonds with coloured gems such as sapphires, emeralds, or rubies.

Art Deco rings commonly incorporated platinum or white gold for gem settings to enhance diamond brilliance, often paired with yellow gold bands. Precise calibre-cut gemstones were individually shaped to fit geometric frames alongside round brilliant or single-cut diamonds.

Authentic pieces usually display fine millegrain border details, hand-set calibre-cut stones fitted seamless within channels, and period-correct metal purity marks. Platinum settings fused onto yellow gold shanks were a standard construction technique of the era.

A geometric Art Deco ring functions as a statement piece that complements both structured contemporary tailoring and evening wear. Its balanced proportion allows it to be worn independently or alongside a simple metal band.

Clean gently using warm water, mild detergent, and a soft-bristled brush to remove dust from behind the settings. Store the ring separately in a fabric-lined box to prevent harder diamonds from scratching precious metals or sapphires.
