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 cluster rings created between 1901 and 1915 are characterized by light, openwork settings, floral motifs, and the prominent use of diamonds alongside coloured gemstones such as sapphires, rubies, and demantoid garnets.

Rings from this period frequently feature platinum or silver-topped gold settings, allowing white metals to accentuate diamonds and coloured stones while maintaining the structural durability of a yellow gold band.

Demantoid garnets exhibit a vivid green colour and high dispersion rate, often displaying characteristic horsetail inclusions of chrysotile fibers when viewed under gemmological magnification.

A historical gemstone cluster ring serves as a focal accessory, pairing well alongside minimalist contemporary bands or worn as a standalone statement piece for formal evening wear.

Clean the setting gently using warm water, mild soap, and a soft-bristled toothbrush, avoiding harsh chemical cleaners or ultrasonic machines that could loosen delicate antique claw settings.
