Apophyllite is a hydrated potassium calcium silicate mineral that crystallizes in the form of pyramidal structures, cubic crystals, as well as druses on matrix or other minerals. The common colour of apophyllite is clear or white, although it can also be found as grey, yellow, red and green. Green apophyllite is the rarest color of all and was found decades ago by an Indian farmer in Poona, India. Since then, green apophyllite can also be found in Brazil and Quebec, Canada. Important localities for common white or translucent forms of apophyllite include India, Australia, Russia, Germany, Greenland, Italy and the USA.
