It is currently not possible to have a "complete list of minerals".
This list contains a mixture of mineral names that have been approved since 1959 and those mineral names believed to still refer to valid mineral species (these are called "grandfathered" species).
Due to the length of this list, it is divided into alphabetical groups.
