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.

A 1950s cocktail ring typically features a large, central focal gemstone mounted in a prominent setting made of platinum or white gold. These designs often incorporate geometric accent stones, such as baguette-cut diamonds, to emphasize the proportions of the main gem.

Mid-century sapphire rings frequently utilize natural Ceylon or Kashmir sapphires paired with diamond accents. The settings are predominantly crafted from platinum or 18-carat white gold to maintain a neutral, cool backdrop that highlights the blue hue of the sapphire.

Authentic Ceylon sapphires are recognized by their distinct cornflower to deep royal blue coloration and high clarity. Period-correct mountings, hand-cut facet patterns, and gemmological laboratory certificates confirming natural origin and lack of heat treatment help verify authenticity.

Vintage jewellery can be styled on a dressing table or vanity using marble trays, glass display domes, or velvet-lined trinket dishes. Storing pieces in open-faced, framed shadow boxes also provides a decorative presentation within a bedroom or dressing space.

Clean platinum and sapphire jewellery using warm water, mild dish soap, and a soft-bristled brush to remove dust and oil. Store the ring in a fabric-lined box separately from other hard gemstones to prevent scratching the platinum mount.
