Apophyllite
Apophyllite is a group of phyllosilicate minerals often found in clear, prism-shaped crystals with a glassy to pearly luster. The colour ranges from colourless and white to green or pink, depending on traces of other elements. Because of its distinctive crystal shape and transparency, apophyllite is popular with collectors and is often found in combination with zeolites.
Major deposits include India, Brazil, Germany, Iceland and the United States. Apophyllite usually forms in the cavities of basaltic lavas and other volcanic rocks by hydrothermal processes. Its general formula is KCa₄Si₈O₂₀(F,OH)-8H₂O, and its hardness is between 4.5 and 5 on the Mohs scale.
