Fire Agate is described as a variety of agate containing inclusions of goethite or limonite, producing an iridescent effect or “fire”.
The color layers are often described like breath on a pane of glass. The thin layers in this material diffract light back to the eye in rainbow patterns of red, green, yellow and blue. The beautiful colors in fire agate may appear as tiny pinpoints, bubbles, bull’s eyes, flashes, specks, swirls or even as a combination of patterns making for endless possibilities. The world’s fire agate deposits stretch from southwest United States to northern Mexico. Fire agate has been reportedly found in at least 15 locations on Arizona such as Slaughter Mountain and Deer Creek.These are photos of various fire agates from Maek Anderson’s personal collection~
This is one of my favorite fire agate gems displaying a pattern described as “the molten effect” or the “crackle effect”.
This is when the finished stone displays internal fissures of color, something like cooling lava.

This is a fire agate gem with an incredible eye-like banded pattern.
This beautiful Slaughter Mountain fire agate has a mirrorlike or metallic
look that is very unusual.
The colors refract with extraordinary brightness including the “royal
mist”, which is a pink-purple,
transparent colored chalcedony layer
above the primary, opaque colors.
