Images of Apophyllite

Apophyllite is an unusual gemstone and generally considered a "collector's gem."  Apophyllite was once thought to be a single mineral, but can actually be divided into two distinct species: fluorapophyllite and hydroxyapophyllite.   Some are still simply called "Aphopyllite" if it is unknown which one kind they actually are. The crystals are found as either glassy prismatic crystals, blocky, or tabular and are colourless, green, pink, or yellow.   It can often be found in basalt or sometimes in the cavities of granite.  Aphopyllite is found in Brazil, India, Germany, Canada, Scotland, and the U.S.
