Apophyllite crystal beds, these mineral specimens come from India and are of high quality, they exhibit excellent crystal forms and clear transparent colouration. Because of this, they are often sought after by many collectors. Apophyllites were originally thought to be a specific mineral, the name, however, refers to a specific class of minerals, the phyllosilicates, as defined in 1978 and comprises of minerals and crystals which have similar chemical makeup that comprise a solid solution series. The name apophyllite is derived from the Greek apophylliso, meaning "it flakes off", as the minerals have a tendency to flake apart when heated, due to dehydration. They are typically found as secondary minerals in the vesicles of volcanic rocks, particularly basalt. These specimens are excellent pieces, they are everything expected form this group of minerals, mostly clear and transparent, some pieces may exhibit a slight green or pink hue. They were collected in Pune (formerly Poona) in India, a well known locality for apophylites and many zeolites which are often found close by. The pieces will come supplied in a card tray ranging from 1.5" x 1.5" to 4" x 3" in dimension according to the size of the specimen (see drop down menu for sizes).
