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.

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 and 1930s is defined by bold geometric patterns, symmetrical arrangements, and high-contrast colour combinations, often combining white metals with black onyx, diamonds, and coloured gemstones.

Pieces from this era typically feature hand-cut natural black onyx, old European or single cut diamonds, set into platinum or white gold mounts, often backed by yellow 18ct gold shanks.

Authentic period pieces exhibit hand-cut gemstone facets such as old European cuts, millgrain edging along metal borders, geometric plaque proportions, and appropriate historic hallmarks.

The geometric monochrome design allows these rings to function as a focal statement piece when paired alongside tailored modern evening wear or minimalist modern attire.

Onyx is a porous stone and requires gentle care using a soft damp cloth, avoiding harsh ultrasonic cleaners, steam, or chemical solvents that could damage the gemstone surface or setting.
