Strictly Vetted Dealers

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.

FAQs

Mid-century cluster rings typically feature a central natural gemstone surrounded by a symmetrical halo of brilliant-cut diamonds set in gold or platinum. Popularised in the 1950s and 1960s, these designs emphasise structured proportions and prominent central focal stones.

These pieces are predominantly crafted from yellow gold or platinum settings, housing natural sapphires paired with round brilliant or single-cut diamonds held in multi-claw mountings.

Authentic pieces generally display period hallmarks, hand-finished basket wirework beneath the head, and gemstone cutting styles characteristic of the mid-20th century.

A classic sapphire cluster ring functions as a focal statement piece that pairs cleanly with tailored contemporary clothing and minimal gold band rings.

Clean using warm water, mild detergent, and a soft brush, ensuring claw settings are inspected periodically by a professional jeweller to maintain structural integrity.
