Chalcedony is a cryptocrystalline form of silica, composed of very fine intergrowths of quartz and moganite.
These are both silica minerals, but they differ in that quartz has a trigonal crystal structure, while moganite is monoclinic.
Chalcedony’s standard chemical structure (based on the chemical structure of quartz) is SiO2 (silicon dioxide).
The name chalcedony comes from the Latin chalcedonius (alternatively spelled calchedonius).
The name appears in Pliny the Elder’s Naturalis Historia as a term for a translucid kind of Jaspis.
The name is probably derived from the town Chalcedon in Asia Minor.
The Greek word khalkedon (χαλκηδών) also appears in the Book of Revelation .
It is a hapax legomenon found nowhere else, so it is hard to tell whether the precious gem mentioned in the Bible is the same mineral known by this name today.
