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 jewellery often features architectural settings, textured metals, and a strong emphasis on highlighting prominent central gemstones framed by clever cluster arrangements.

These pieces typically utilise high-purity precious metals such as platinum or white gold, combined with natural corundum gemstones and brilliant-cut diamond accents.

Authenticity is assessed through hallmark stamps, appropriate metal oxidation, prong-setting techniques characteristic of the era, and gemmological reports confirming stone treatments.

A statement ring works best as a focal point, paired with minimalist attire to let the historic craftsmanship and unique gemstone take centre stage.

Store pieces separately in lined boxes to prevent scratching, clean gently with warm soapy water and a soft brush, and avoid harsh ultrasonic cleaners.
