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 from the 1930s features geometric forms, streamlined linear drops, and the prominent use of platinum or white gold. Gemstones were frequently cut into drop shapes and paired with accent diamonds to create contrast.

Pendants from this era commonly utilise 18ct white gold or platinum settings to securely hold central gemstones such as opals, sapphires, or emeralds, often accented by small round brilliant-cut diamonds.

Authentic pieces feature period-correct metal hallmarks, claw or bezel settings crafted by hand, and linear drop constructions rather than modern cast fittings. Natural opals from this era display organic colour play rather than synthetic uniform patterning.

A vertical drop pendant can be worn against neutral necklines or layered with understated fine chains to highlight the iridescent play of colour within the central stone.

Opals are delicate gemstones requiring protection from high heat, sudden temperature shifts, and harsh chemicals. Clean gently with a soft cloth and store separately from harder gemstones to prevent surface scratching.
