Agate is the name given to a group 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.  In some specimens, the banding stops meaning the deposition has not proceeded far enough to fill the cavity resulting in a hollow space.  The final deposit usually consists of quartz crystals that fill the open space. 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.
