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.

FAQs

The Art Deco period spans roughly from the 1910s to the 1930s, characterised by geometric precision, stylised motifs, and a transition away from the flowing curves of Art Nouveau towards modern industrial aesthetics.

Jewellery from this era frequently combined yellow gold or platinum settings, often featuring hand-cut gemstones secured in precise claw or bezel settings with millegrain detailing.

Authentic pieces typically display hand-cut stones such as old European or old mine cuts, traditional assay hallmarks, and signs of period craftsmanship including hand-engraved details and natural gemstone inclusions.

An antique three-stone ring serves as a sophisticated statement piece that pairs well with contemporary minimalist bands or can be worn alone as a striking focal point for daily wear.

Preserve antique jewellery by storing pieces individually in soft pouches, avoiding harsh chemical cleaners, and having the setting security checked periodically by a professional jeweller.
