Historical and Geological Background:

Fortification Agate gets its name from its distinctive angular concentric bands, which resemble the walls of a fortress when viewed in cross-section. These formations occur as silica-rich fluids seep into rock cavities over millions of years, depositing layer upon layer of chalcedony and quartz.

Agates with fortification patterns are found in many parts of the world, including Brazil, Uruguay, Mexico, Botswana, and the United States (notably in Montana and Oregon). Historically, agates with strong fortification patterns were prized for amulets and protective talismans — the fortress-like imagery was seen as a metaphysical barrier against negative forces.

In lapidary work, Fortification Agate is valued for its durability, high polish, and striking visual patterns, which can range from delicate zigzags to bold, architectural outlines.
