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.

FAQs

A natural black opal features a dark body tone ranging from dark grey to black, which enhances the play-of-colour and makes vibrant spectral hues like red, green, and blue stand out more intensely than in white opals.

Nine-carat gold consists of 37.5 percent pure gold alloyed with other metals to increase durability and strength, making it a popular choice for everyday jewellery mounts and chains.

Authentic natural opals typically exhibit irregular, unique play-of-colour patterns under magnification, whereas synthetics often display a columnar or lizard skin pattern when viewed from the side.

A pendant necklace functions well as a focal point when paired with minimalist necklines or layered with finer, shorter chains for a contemporary textured look.

Opals contain water and are sensitive to sudden temperature changes and harsh chemicals; they should be cleaned gently with warm soapy water and stored away from direct sunlight.
