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.

FAQs

Synthetic corundum, including colour change sapphire and alexandrite-type spinel or sapphire, became commercially viable in the late 19th and early 20th centuries following the development of the Verneuil flame-fusion process in 1902. These stones were widely utilised in Edwardian and Art Deco jewellery to achieve vivid colour and large carat weights at an accessible price point.

Antique rings of this type are typically crafted from 9 carat rose gold, often alloyed with copper to achieve the characteristic warm pinkish hue. Stones are traditionally hand-set in claw or collet settings, with hand-finished shanks displaying the hallmarks or stamps typical of early 20th-century assay offices.

Authentication involves examining hallmarks, laser-welding signs, casting porosity, and wear patterns on the metal. Antique pieces frequently exhibit hand-carved details, period-appropriate assay marks, and patination consistent with age, whereas modern reproductions often lack these subtle manufacturing anomalies.

An antique cocktail ring serves as a focal point and can be worn alone to highlight its design or paired with contemporary minimalist gold bands for a mixed-era aesthetic. It bridges vintage charm with modern styling when contrasted against neutral fabrics and contemporary silhouettes.

Maintain antique jewellery by cleaning it gently with warm soapy water and a soft brush, avoiding harsh chemical dips or ultrasonic cleaners which can damage historical settings or softer stones. Store pieces individually in fabric-lined boxes to prevent scratching the gold and gemstones.
