Historical and Scientific Facts:

• Fire agate is a rare variety of layered chalcedony quartz with a beautiful fiery iridescent effect. It can only be found in Northern Mexico and some of the South Western United States. 
• The reason for its iridescent appearance is because when light passes through the different layers composed of limonite or goethite iron oxide and silica, it causes a prism effect that causes the light to separate into various colors. This is what distinguishes it from all other agates.
