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. In fact, since our founding in 2002, Sellingantiques has only had to step in to help resolve an issue on roughly five occasions—a true testament to the quality of our dealers and their dedication to your happiness.
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, originating in the 1920s and 1930s, is characterised by geometric forms, bold gemstone color combinations, linear symmetry, and refined metalwork inspired by the modern industrial movement.

Jewellers during the Art Deco era frequently paired platinum or white gold with diamonds and vibrant coloured accent gemstones, including sapphires, emeralds, and rubies.

Authentic pieces generally display platinum settings, fine millegrain border detailing, geometric step-cut gemstones, hand-engraved motifs, and period-appropriate maker marks.

An Art Deco ring functions as a standalone statement piece that complements contemporary tailored evening wear as well as minimal everyday wardrobe essentials.

Clean gently using warm water, mild soap, and a soft toothbrush, avoiding harsh chemicals, ultrasonic baths, and abrasive materials to protect set stones and fine metalwork.
