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

Originating in the 1920s and 1930s, Art Deco jewellery is characterized by geometric patterns, bold colour contrasts, and symmetrical arrangements. Jewelers frequently combined diamonds with vibrant coloured gemstones, such as sapphires, set in white metals like platinum.

Art Deco cluster rings were predominantly crafted using platinum or white gold to showcase white diamonds and vibrant gemstones. Custom-cut calibre sapphires, rubies, and emeralds were regularly fitted around central diamonds with hand-applied milgrain edge detailing.

Authentic pieces typically feature hand-cut gemstones, geometric target or marquise shapes, and fine milgrain borders. Inspecting the metal hallmarks for platinum purity and observing precision metalwork under magnification helps confirm period authenticity.

An Art Deco cluster ring functions effectively as a focal statement piece when paired with clean, minimalist contemporary tailoring. It can be worn individually on the right hand or stacked alongside unadorned platinum bands.

Clean the setting gently using warm water, mild soap, and a soft-bristled brush to remove dust and oils. Store the ring separately in a fabric-lined box to prevent harder diamonds from scratching surrounding metals and gemstones.
