The Sustainable Choice

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.

FAQs

Art Deco jewellery from the 1920s is characterised by bold geometric lines, symmetrical patterns, and high-contrast gemstone combinations. The period favoured platinum settings, step-cut gemstones like emerald cuts, and intricate diamond accent work such as pave and channel settings.

Art Deco sapphire rings were predominantly crafted using platinum, which allowed for lightweight yet durable settings. Central gemstones often included natural sapphires, frequently sourced from Ceylon or Burma, surrounded by round or baguette-cut diamonds.

Authentic pieces typically feature hand-cut gemstones, fine milgrain edging, and precise hand-carved geometric under-gallery work. Hallmarks, makers marks, platinum stamps, and the absence of modern casting seams or computer-aided manufacturing indicators further confirm authenticity.

An antique sapphire ring serves as a focal accessory that can be worn alongside tailored evening wear or minimalist modern outfits. Pairing the piece with simple silver or platinum jewellery allows the gemstone and detailed geometric setting to remain prominent.

Clean the ring using warm water, mild soap, and a soft-bristled brush to remove dust and oils from behind the gemstone mount. Avoid harsh chemical cleaners, and store the piece individually in a lined box to prevent diamonds from scratching adjacent metalwork.
