FAQs

Onyx and diamond combinations gained immense popularity during the Victorian era and saw a dramatic revival during the Art Deco period, where high-contrast black and white designs were favoured for their striking geometric elegance.

These pieces traditionally feature natural black chalcedony (onyx), genuine diamonds, and precious metals such as yellow or white gold, often hallmarked to denote purity and origin.

Authentic pieces typically bear clear metal hallmarks, secure prong or bezel settings for the stones, and natural inclusions visible under magnification in both the diamonds and the opaque quartz.

A bold black and white cluster ring acts as a focal point, pairing well with minimalist silver or gold bands for a contemporary mixed-metal stack or worn alone as a standalone statement piece.

Onyx is a softer gemstone than diamond, so it should be cleaned with mild soapy water and a soft cloth, avoiding harsh ultrasonic cleaners or chemicals that could damage the stones surface.
