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.

Edwardian bar brooches, crafted between 1901 and 1910, are defined by delicate metalwork, linear silhouettes, and the prominent use of platinum or white gold alongside precious gemstones such as opals, pearls, and diamonds.

Jewellers during the Edwardian era favoured 18ct gold, platinum, or platinum-faced settings paired with vivid fire opals and accent diamonds arranged in fine, geometric mountings.

Authentic Edwardian brooches typically feature fine claw settings, hand-cut gemstones, period hallmarks, and traditional long pin mechanisms with simple safety catches or tube hinges.

An antique brooch can be displayed inside a framed shadow box, mounted on a velvet display stand within a glass cloche, or incorporated into a curated dressing table tray layout.

Store fire opal pieces away from direct sunlight, heat, and dry environments, avoid immersion in water or ultrasonic cleaners, and gently wipe metal surfaces with a soft cloth.
