Petalite is a feldspar mineral, also known as Castorite. It is a pale pink, white or sometimes transparent mineral in the monoclinic system. It was named by the Brazilian naturalist Jose Bonifacio de Andrada e Silva, the name being derived form the Greek word ‘petalon’ which describes it’s perfect leaf like cleavage. Early industrial uses for petalite were in the production of glass ceramic wares, such as many early cook ware items. However, in the modern day, its most important use is that it is a source of lithium, an element which today is found in most batteries for portable devices such as tablets, phones, laptops and more. These particular specimens come from Bikita, Zimbabwe, a well known economic source of petalite. These specimens are available in limited sizes & are supplied in a card tray with information label.
