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.
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.
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.

Engagement rings from the 1940s often feature transitional or old European cut diamonds set in mixed metals, combining yellow gold bands with white gold or platinum claw settings. The design era bridges late Art Deco geometric elements with classical, streamlined solitaire styling.

During the 1940s, jewellers typically crafted engagement rings using 18ct yellow gold for the shank paired with platinum or white gold setting heads to enhance the white appearance of the diamond.

Authentic pieces from this period feature hand-cut facet patterns typical of old European or transitional cuts, alongside period hallmark stamps inside the band and hand-finished claw collets.

A classic mid-century diamond solitaire can be effortlessly paired with modern minimalist gold bands or stacked alongside textured vintage wedding rings for a multi-tonal aesthetic.

To preserve a vintage diamond ring, clean it gently using warm water, mild soap, and a soft-bristled brush, while scheduling regular professional inspections to check claw integrity.
