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

Black diamonds, historically known as carbonado, gained popularity in contemporary fine jewellery during the late twentieth century as modern gemstone settings evolved to showcase contrasting monochromatic designs.

These rings are typically constructed from high-purity platinum, featuring a central treated or natural black diamond supported by brilliant-cut white diamond accents along the metal shoulders.

Authentic pieces carry official hallmarking stamps denoting platinum purity, alongside professional gemmological verification to confirm stone authenticity and diamond weight.

Fine rings are often showcased on velvet ring stands or within lined glass jewellery caskets positioned on dressing tables or vanity tops.

Clean gently using warm water, mild liquid soap, and a soft-bristled brush, avoiding harsh ultrasonic cleaners if the black diamond has undergone heat enhancement.
