Agate is not really a gemstone, but rather a set of microcrystalline varieties of quartz (silica). Actually, they are varieties of chalcedony which have bands of multiple colors with little contrast. Agate can be found in volcanic rocks whose size can range from very small (only a few millimeters) to several meters.
