Fire agate is a unique variety of agate known for its fiery hues and iridescence. Agate is a translucent subtype of chalcedony (microcrystalline quartz). Fire agates are one of the few iridescent varieties, though their bubble-like botryoidal shape is more common for agates.
The red, brown, and orange base colors, along with the stone’s iridescence, comes from layers of iron oxide inclusions like goethite or limonite. Fire agate may be heated to have a crackled look.
