Onyx

Onyx takes its name from the Latin onyx, meaning both “nail” and a type of agate, referring to chalcedonies whose pale tones once resembled the colour of a fingernail. Today, the term primarily describes deep black or rich green varieties within the chalcedony family. Found in Brazil, the United States, India, Madagascar, Mexico and Uruguay, onyx is a decorative stone known for its polished, opaque surface — smooth, lacquer-like and visually impactful. During the reign of Queen Victoria, black onyx became the official stone of mourning for nearly forty years, with other shades prohibited. Beyond this historical association, it has since become a contemporary material valued for its clean, graphic presence. Designers such as Sophie Buhai and Viltier use black or green onyx to craft striking, sculptural pieces. In various traditions, onyx is associated with motivation, strength and support during periods of physical or mental stress. A stone that combines structure, intensity and a distinctive, modern elegance.
