Agate Carved Crystal Neolithic an average adult Triceratops wasAgate 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. Igneous rock is formed by lava and volcanic activity. This activity can form pockets bubbles in the rock, similarly to Swiss cheese. When these pockets are formed in an area close to water, the water
