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

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

A diamond solitaire ring features a single, prominent diamond mounted on a precious metal band, designed to showcase the stone as the primary focal point.

These rings are typically crafted from precious metals such as platinum, yellow gold, white gold, or rose gold, paired with a diamond centre stone.

Diamond quality is assessed using the four Cs: cut, colour, clarity, and carat weight, which determine the brilliance and overall value of the stone.

The understated design of a solitaire ring allows it to pair easily with other jewellery pieces, making it suitable for both daily wear and formal occasions.

Regular cleaning with warm soapy water and a soft brush, alongside professional inspections of the prongs, helps maintain the sparkle and structural integrity of the piece.
