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.

Crescent moon brooches became exceptionally popular during the late Victorian and Edwardian periods, continuing into the 1920s. Celestial motifs represented change, spirituality, and femininity, often gifted as tokens of affection.

Pieces from this era frequently feature precious metals such as yellow gold or platinum, set with natural gemstones including sapphires, diamonds, rubies, or pearls in grain or claw settings.

Authentic period pieces display period-appropriate metal purity hallmarks, hand-finished stone settings, characteristic gem cuts such as cushion or mine cuts, and original safety chain fittings.

An antique brooch can be styled on suit lapels, attached to the collar of a blouse, used to secure a silk scarf, or pinned into hair accessories for formal occasions.

Clean gently using lukewarm water, mild liquid soap, and a soft-bristled brush, then dry thoroughly with a lint-free cloth. Inspect settings periodically to ensure all gemstones remain securely fastened.
