Fossil coral should not be mistaken for endangered or protected reef coral or precious coral. It is considered to be a type of agate or chalcedony, rather than a type of coral, due to its silicon dioxide composition (SiO2). Coral deposits have been mined and commercialized for their high calcium, potassium, magnesium and sodium content, and are often used for the making of health and drug supplements. Fossil coral is used in industrial fertilizers and water purification filters because it can remove chemical impurities such as chlorine and formaldehyde.
