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 diamond jewellery from the 1920s and 1930s is defined by geometric motifs, precise stone setting techniques, and the frequent pairing of platinum tops with yellow gold bands.

These rings commonly utilised 18ct yellow gold, platinum, and diamonds, with platinum chosen for its structural strength and white finish that enhances diamond brilliance.

Authentic pieces feature period hallmarks, platinum-faced mountings on gold shanks, and period stone cuts such as old European or single cut diamonds.

An Art Deco ring can be worn as a standalone focal piece or paired alongside minimalist contemporary jewellery and neutral modern tailoring.

Clean the piece using warm water, mild soap, and a soft-bristled brush, ensuring periodic professional checks of the claws and settings.
