Every single antique dealer on our platform is individually approved by our internal team. We verify their professional trade history, ethical standards, and photographic quality to ensure a secure, high-standard buying environment. Upon joining, every dealer agrees to a strict 9-point code of conduct. While issues can occasionally arise, our dealers typically resolve them swiftly and directly with the buyer.

Our dealers are highly experienced in packing and shipping fragile, high-value antiques. Because you are in direct contact with the dealer, you will be able to easily go through all available shipping and insurance options together to ensure your item arrives safely.
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 patterns, bold linear shapes, and precise symmetry. Platinum became the preferred metal during this period, often paired with diamonds and detailed hand-engraving.

Art Deco engagement rings predominantly utilise platinum or white gold to showcase the white brilliance of diamonds. Construction often features die-struck mountings, filigree work, milgrain edging, and hand-carved shoulder details.

Authentic pieces usually feature period hallmarks, hand-engraved motifs rather than cast details, and specific diamond cuts such as Old European Cut or Transitional Cut. Settings frequently exhibit fine milgrain work and precise geometric mountings consistent with early 20th-century manufacturing techniques.

An Art Deco diamond ring pairs well with simple contemporary metal bands or thin diamond-set eternity rings. Its neutral white metal tone allows versatile pairing alongside both modern minimal jewellery and traditional antique pieces.

Clean the ring using warm water, mild soap, and a soft-bristled brush to remove dust and oils. Professional annual inspections ensure the prongs remain secure and the platinum retains its structural integrity.
