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

Clean gently using warm water, mild soap, and a soft-bristled brush, and store the piece separately in a lined jewellery box to prevent scratching from harder metals or stones.

An antique ring works well when worn as a standalone statement piece or stacked with minimalist modern bands to create a deliberate contrast between eras.

Authentic pieces typically exhibit period-specific hallmarks, hand-cut gemstones like old mine or European cuts, and fine metalwork craftsmanship characteristic of the 1920s and 1930s.

These pieces frequently utilise 18-carat yellow or white gold and platinum settings, paired with natural gemstones such as sapphires, rubies, emeralds, and old-cut diamonds.

A Moi et Toi ring features two main gemstones set side-by-side or intertwined, symbolising two souls meeting as one, a style that gained immense popularity during the late 19th and early 20th centuries.
