Agate is a variety of silica also sometimes known as “banded chalcedony.” It is most fashion often formed as nodules in volcanic rock. A vapor vesicle in the rock fills in over time with layers of chalcedony and crystalline quartz. When the cavity does not fill in completely there will be a geode center with the crystal points directed toward the interior of the specimen. The stone was named after the river Achates (now known as Dirillo and located in modern day Sicily) by the Greek naturalist Theophrastus. Agate has a long history of use for artistic and decorative purposes.
