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.

FAQs

Art Deco ruby solitaire rings from the 1930s typically feature central gemstones set in precious metals, often complemented by geometric shoulders accented with smaller diamonds.

Jewellers in the 1930s frequently combined platinum or white gold bands with contrasting yellow gold claw settings, alongside unheated natural rubies and accent diamonds.

Authentic 1930s rings often showcase geometric shoulder detailing, precise claw or bezel settings, period hallmarks, and natural gemstone inclusions visible under magnification.

A vintage ruby solitaire ring serves as a focal piece that pairs directly with modern tailored eveningwear or contemporary casual outfits.

Clean vintage ruby jewellery using warm soapy water and a soft brush, avoiding chemical cleaners or ultrasonic treatments to protect the antique mounting.
