Agate is a banded form of chalcedony, a microcrystalline variety of quartz (SiO₂). It forms when silica-rich groundwater fills cavities inside ancient volcanic rock, depositing layer after layer over thousands to millions of years. These slow, rhythmic deposits create agate’s signature concentric bands, often resembling topographic lines or fortification walls.
