Collection: ONYX

Onyx is a variety of chalcedony, a microcrystalline form of quartz, known for its smooth texture and typically black color, sometimes showing white or colored banding. It forms in volcanic rocks where silica-rich water slowly deposits layers over time inside cavities and fissures. Historically, onyx has been used since ancient Egypt and Rome for carved cameos, seals, and decorative objects due to its ability to hold fine detail when cut. Today, it is widely used in jewelry and interior decoration, appreciated for its sleek, polished appearance and bold, minimalist look.
