Brazilian Agate "Crystal" Barite In this slow processAgate is a form of Chalcedony, made up of 90% quartz and 10% morganite. It is composed of microscopically fine fibrous crystals, and it normally shows color banding, stripes, whirls, bull's eye and other random patterns due to impurities in the quartz.
