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.

An Edwardian ring displays a traditional boat shape rendered in 18ct yellow gold, hallmarked in Birmingham in 1912. The setting holds three blue sapphires interspersed with four accent diamonds within a carved gallery structure. Visible elements include bright yellow gold metal, deep blue oval gemstones, and small brilliant-cut stones arranged horizontally across the finger. The visual composition includes a vintage ring box lined with dark blue velvet upholstery, a metal hinge mechanism at the front, and a circular stamped gold inscription inside the lid. UK ring size is M 1/2 and US size is 6.5, with a face dimension of 13.3mm by 7mm. The piece is worn on the hand as a personal adornment.

FAQs

A boat ring, or boat-head ring, features an elongated gallery setting tapering at both ends, designed during the Victorian and Edwardian eras to display multiple gemstones across the finger.

Edwardian rings typically combine 18ct yellow gold, platinum, or silver settings with precious gemstones such as sapphires, diamonds, and rubies, frequently featuring hand-carved galleries.

Authentic British Edwardian pieces bear clear hallmarks including a crown, gold purity rating, assay office symbol, and date letter indicating manufacture between 1901 and 1914.

An antique boat ring can be worn as a standalone focal piece on the hand or stacked alongside plain gold bands to complement contemporary jewellery styles.

Clean gently using warm water, a mild detergent, and a soft toothbrush, avoiding harsh chemical cleaners, ultrasonic devices, and sudden temperature fluctuations.
