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 jewellery, produced between 1901 and 1915, is defined by delicate garland motifs, light filigree work, and the prominent adoption of platinum to highlight bright diamond settings.

Rings from this era frequently combined platinum mountings with hand-cut diamonds, allowing jewelers to create intricate, lace-like metalwork with structural integrity.

Authentic pieces exhibit hand-cut gemstones like old European cut diamonds, fine milgrain borders, engraved shanks, and lightweight pierced platinum settings rather than modern cast metal.

An antique engagement ring can be worn as a standalone statement piece or stacked with a simple, slim metal band to complement detailed metalwork on the shoulders.

Clean the ring gently using warm water, mild soap, and a soft brush, ensuring periodic inspections by a professional jeweler to verify setting security.
