Strictly Vetted Dealers

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.

Secure Transit

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.

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 defined by geometric patterns, clean symmetry, contrasting gemstone combinations, and intricate metalwork such as filigree and millgrain setting.

Platinum and high-carat white gold were the primary metals used, frequently set with old European cut diamonds alongside accent gemstones like calibre cut sapphires, emeralds, or rubies.

Authentic pieces feature hand-cut gemstones, such as old European or mine cuts, hand-carved filigree detailing, characteristic geometric mount construction, and era-appropriate metal hallmarks.

An Art Deco ring functions as a standalone statement piece, pairing naturally with modern minimal wedding bands, stacked silver or platinum jewellery, or tailored contemporary attire.

Clean gently using lukewarm water, mild liquid soap, and a soft-bristled brush, avoiding ultrasonic cleaners if delicate filigree or channel settings show wear, and store separately to prevent scratching.
