Mineral (Chalcedony)

Historical & Geological Background

Chalcedony is a microcrystalline variety of quartz composed primarily of silicon dioxide (SiO₂). It forms in volcanic and sedimentary environments where silica-rich solutions slowly crystallise within cavities and fractures in host rock.

Its wide range of colours results from trace elements and mineral inclusions present during formation, leading to varieties such as agate, onyx, and jasper. Chalcedony has been used historically for carvings, seals, and ornamental objects due to its durability and smooth texture.
