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

Art Deco trilogy rings typically feature three central gemstones arranged in a line, symbolising the past, present, and future. Produced during the 1920s, these rings often blend platinum mounts with yellow gold shanks and display geometric claw settings.

Pieces from this era frequently utilise eighteen-carat yellow gold for the band paired with platinum crowns or claws to enhance the white appearance of diamonds and contrast with coloured gemstones.

Authentic 1920s rings usually feature hand-cut diamonds, such as old European cuts, alongside natural sapphires. Markings inside the band, such as 18CT and PLAT, indicate period-correct metal alloys.

An antique trilogy ring serves as a focal piece that pairs well with plain platinum or gold bands. Its mixed-metal construction allows it to complement both warm and cool-toned contemporary jewellery.

Clean the gemstones using warm water, mild soap, and a soft-bristled brush. Avoid harsh chemical cleaners and ultrasonic devices, and have a jeweller periodically inspect the platinum claws to ensure structural integrity.
