Agate is a banded Chalcedony, essentially a microcrystalline or cryptocrystalline quartz whose individual crystals are microscopic, and thus gemstones are comprised of numerous, rather than individual crystals.
Individual bands can be one or multi-coloured, and often red (Carnelian), pink and brown, separated by greys. The common treatment is dying producing blue, green and red agate without banding.
