Agate is a variety of chalcedony, which is the general term applied to fibrous cryptocrystalline quartz varieties. It is a mineral generally of secondary origin, forming in cavities and veins by deposition from meteoric groundwater containing gelatinous silica from the weathering of silicate minerals. It can also form by deposition from late hydrothermal solutions at or near the earth's surface under conditions of low temperature and low pressure. Agate is commonly associated with siliceous volcanics, occurring as vein or vesicle filling. It occurs as a petrifying agent in fossil wood and bone. Agate is frequently found lining or filling rock cavities and fissures, sometimes forming geodes.

Agate is said to enhance one's perceptiveness and to stimulate analytical capacity, and to provide balance between one's physical, emotional, intelectual and spiritual states. Agate is also said to alleviate hostilities and promote goodwill. Agate is said to help treat disorders of the pancreas and to improve circulation.

All gemstones should be protected from sharp blows, harsh chemicals, and extreme temperatures. Some particularly sensitive gemstones should even be kept away from strong light sources, as such exposure may cause color fading. Gemstones should be stored in a dry, safe place.
