As the mineralogical system evolves, the list of minerals slowly grows. There are new minerals discovered every year. Nearly 4000 mineral species are known but unfortunately only few hundreds are common. Some others are discarded in time because of changes in mineralogical system, their obsolete definition or other reasons. The International Mineralogical Association (IMA) is responsible for keeping up-to-date records of mineral list and also approves new minerals and discards the obsolete. You can download their full list of minerals in PDF.
