Chalcedony is any form of microcrystalline or cryptocrystalline quartz, (meaning any form of quartz whose crystals are too small to be seen without high magnification.) Usually only the translucent, single-colored types are sold as "Chalcedony" whereas the rest of this group are sold under individual variety names, or subcategories such as jasper or agate. Jasper usually refers to an opaque, solid or multi-colored stone often with patterns. Agate is defined either by its translucency, or by having banding or stripes. onyx, sardonyx, chrysoprase, carnelian, and bloodstone are forms of Chalcedony.

Chalcedony can be found in Iceland, India, Mexico, Namibia, Brazil, Egypt, India, Uruguay, Brazil, Uruguay, and Australia. In the United States it is mostly located in California, Nevada, Oregon.

The name Chalcedony comes from the Latin word "chalcedonius", which is believed to come from a Greek word for the ancient port of Chalcedon, near present-day Istanbul. Chalcedony was used in tool making as early as 32,000 BP in Central Australia. Rev 21:19 in the Bible, Chalcedony is listed as the third foundation stone of the New Jerusalem.
