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.

This vintage fine jewellery ring originates from the 1950 period and functions as a standalone solitaire piece. The construction incorporates 14ct yellow gold, shaped into a polished band with stepped shoulder details and a bezel setting that holds a black boulder opal. The central oval cabochon stone displays a play of blue, red, orange and green colour across its surface, framed by a twisted rope border around the bezel. A hallmark is stamped into the metal indicating the 14ct gold standard alongside the stone weight. Measuring 1.6 cm high by 1.3 cm wide and 2.2 cm deep, the ring is sized as a UK size S with a total weight of 3.0 grams. It sits comfortably as a wearable personal accessory for everyday adornment or special occasions, functioning as a distinctive hand ornament that pairs easily with other fine jewellery collections.

FAQs

A boulder opal solitaire ring features a single natural boulder opal gemstone, characterised by host rock backing that enhances play-of-colour, mounted in a metal band.

Antique opal rings are commonly set in solid yellow gold, rose gold, or platinum, featuring bezel or claw mountings to secure the delicate cabochon stone.

Authentic boulder opals exhibit irregular natural ironstone backing visible on the underside, displaying unique play-of-colour patterns rather than uniform synthetic flashes.

A vintage gemstone ring can be worn as a singular accent piece alongside minimalist modern jewellery or stacked with simple unadorned gold bands.

Opals require gentle care; clean using a soft cloth with warm water and mild soap, avoiding chemical cleaners, steam, and prolonged water immersion.
