Apophyllite was first discovered in 1806 and was named after the Greek word meaning 'leaf' or 'to flake' because it tends to crumble when heated. Although some people may not have heard of this gem it is actually found all around the world with large deposits in Japan, USA, India, Canada, Germany and Norway just to name a few. It has been used by mystics throughout history for fortune telling and astral travel.
Found in volcanic zeolite environments, Apophyllite was formerly categorised as being one single mineral but in 1978 it was classified as including two minerals, fluorapophyllite and hydroxyapophyllite. Then, in 1981 another mineral was included, natroapophyllite, so it is made up of a group of minerals with a similar chemical make up. Apophyllite is a hydrated potassium calcium silicate that forms in transparent pyramid, cubic and druzy formations. It has a hardness of 4.5-5.
