What is an 18ct solitaire diamond band?

An 18ct solitaire diamond band is a ring featuring one single diamond set into an 18-carat gold band. These pieces range from antique Victorian designs to mid-century modern examples. The single stone design focuses attention entirely on the cut and quality of the central diamond, supported by durable precious metal.

How do I date an antique diamond ring?

Dating involves examining the cut of the diamond, the metal combinations, and the overall style of the setting. Old European cuts and platinum-topped gold settings often point to the Edwardian or Art Deco eras. Hallmarks and specific mounting styles, such as gypsy settings or geometric shoulder work, also provide clear chronological markers.

Are these rings suitable for everyday wear?

Most 18ct gold and platinum rings are built to withstand daily use, especially heavier styles like gypsy or belcher bands. The hardness of gold and diamonds makes them practical for regular wear as engagement or wedding rings. Lighter antique settings may require slightly more mindful wear to protect delicate claws and smaller shoulder stones.

What is the difference between white gold and platinum?

White gold is an alloy of yellow gold mixed with white metals to achieve a silvery tone. Platinum is a naturally white, denser, and extremely durable metal. Many antique rings combine both, using 18ct gold for the band and platinum for the settings to hold the diamond securely.
