Gemological info: Agates are created from nodular masses in rock, like volcanic and certain metamorphic rocks. When split open, they reveal a variety of patterns, colors, and bands that distinguish the gemstone from other forms of Chalcedony. Agates are made of fibrous chalcedony (cryptocrystalline silica) and the fibers in thin slices are sometimes visible in a transmitted light which causes interesting optical effects.
