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.

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

Tanzanite was discovered in Tanzania in the late 1960s and quickly gained prominence in high-end jewellery design due to its unique trichroic violet-blue colour.

These rings are typically crafted from 18-carat yellow or white gold, featuring precision-set gemstones secured with traditional claw or bezel settings.

Authenticity is verified through official hallmark stamps indicating metal purity, microscopic examination of setting wear, and professional gemological certification.

This versatile piece works well as a standalone statement ring or paired with minimalist gold bands for an elevated everyday look.

Clean gently using warm soapy water and a soft brush, avoiding harsh ultrasonic cleaners and chemical exposures to protect the softer tanzanite stone.
