Strictly Vetted Dealers

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.

Secure Transit

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.

The Sustainable Choice

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.

FAQs

Preservation requires storing pieces individually in soft-lined compartments to prevent scratching, cleaning periodically with warm soapy water and a soft brush, and avoiding harsh ultrasonic cleaners on treated stones.

Such rings are typically worn as statement pieces on the hand, paired with minimalist attire to allow the intricate gemstone arrangement and metalwork to remain the visual focal point.

Authentication involves examining hallmarks for metal purity, inspecting stone inclusions under magnification, and performing thermal conductivity or refractive index tests via a professional gemmologist.

Cluster rings traditionally utilise precious metals such as 18-carat yellow, white, or rose gold, alongside platinum, with stones secured via prong, bezel, or channel settings to ensure structural integrity.

The marquise cut, featuring an elliptical shape with pointed ends, dates back to the 18th century in France and gained popularity for its ability to maximise perceived carat weight and finger coverage.
