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, prominent from 1920 through the 1930s, is characterised by geometric shapes, clean lines, low-profile settings, and the widespread use of platinum to highlight white diamonds.

Rings from this era were predominantly crafted in platinum or white gold, featuring hand-cut diamonds such as Old European or transitional cuts, often detailed with millgrain edges and hand-engraved shoulders.

Authentic pieces display period hallmarks, hand-carved decorative motifs, millgrain borders, and hand-cut diamonds featuring smaller table facets, higher crowns, and open culets typical of early twentieth-century lapidary work.

The low-profile bezel setting pairs seamlessly with understated modern metal bands, allowing the historic diamond cuts to stand out alongside contemporary aesthetic choices.

Clean gently using warm water, mild dish soap, and a soft-bristled brush. Avoid harsh chemicals, and have a professional jeweller inspect the bezel or claw settings periodically to ensure stone security.
