Agate is the name given to a group of aggregates of various forms of silica, chiefly chalcedony. They form in nodules or holes in ancient lava flows. Water slowly percolates through the nodule depositing silica from the cooled lava in regular layers. Sometimes the silica contains minerals, when this happens a banding effect is visible. The final deposit usually consists of quartz crystals directed toward the free space in the center. This is called a geode. Agate is a unique mineral that was once thought to protect its owners from danger and even produce delightful dreams.
