Light green apophyllite is commonly found in volcanic rocks and basalt cavities. It often forms in association with other minerals such as stilbite, calcite, and heulandite with a composition of KCa4Si8O20(F,OH)·8H2O (hydrated potassium calcium silicate fluoride).
It possess a Tetragonal crystal system with a hardness of 4.5-5 on the Mohs scale. Its cleavage is perfect in one direction, which can make the crystals appear to have flat, mirror-like surfaces. Its luster is vitreous (glassy) to pearly and is transparent to translucent. Usually white, colorless; also blue, green, brown, yellow, pink, violet
Notable sources include the Deccan Traps in India, particularly in the Maharashtra region, as well as other parts of the world like Brazil, Canada, and the United States.
