Fire Agate is a variety of layered chalcedony quartz which exhibits a fiery iridescent effect and it is a natural gemstone found only in the surrounding areas of the Southwestern United States and Northern Mexico.
Iridescence is an optical phenomenon caused by light diffraction. As light passes through different layers of material, a prism effect causes light to separate into various spectral colors.
With fire agate is composed of alternating layers of limonite or goethite iron oxide and silica. It is the unique internally layered composition that distinguishes fire agate from any other variety of agate.
