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, popular during the 1920s and 1930s, is defined by geometric patterns, streamlined forms, and the prominent use of platinum alongside diamonds and coloured gemstones.

1930s rings frequently utilised platinum or 18ct white gold to achieve a cool metallic lustre, paired with hand-cut diamonds such as Old European or transitional cuts.

Authentic pieces typically display hand-engraved detailing, milgrain edging, specific hallmark stamps, and hand-cut diamonds featuring a smaller table and higher crown compared to modern brilliant cuts.

An Art Deco diamond ring offers a classic aesthetic that complements minimalist modern tailoring, slim secondary bands, or stacked vintage rings for a contemporary jewellery look.

Clean gently using warm water, mild soap, and a soft-bristled brush, ensuring settings are regularly checked by a professional jeweller to maintain secure stone retention.
