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.

Cocktail rings originated in the 1920s and gained widespread popularity in the 1950s, characterised by large central gemstones framed by accent diamonds or decorative metalwork designed for evening wear.

Mid-century aquamarine rings are frequently crafted in platinum or 18ct white gold to complement the cool blue tones of the beryl, often set with accent diamonds in claw or grain settings.

Authentic mid-century rings often feature hallmark stamps indicating gold purity, precise hand-finishing, millegrain edging, and substantial emerald-cut or cushion-cut gemstones.

Statement cocktail rings can be worn as singular focal pieces for formal attire or displayed in lined velvet jewellery boxes and glass-topped vitrines when not worn.

Clean aquamarine jewellery using warm water, mild liquid soap, and a soft-bristled brush, avoiding ultrasonic cleaners if the stone contains inclusions, and store separately to prevent scratches.
