Zeolite - Apophyllite Specimen Malachite terminated crystalsWeight: 979g Measurements: 156mm x 89mm x 64mm (All measurements are approximate) APOPHYLLITE A hydrated potassium calcium silicate mineral known as apophyllite can form druzy crystals, pyramidal structures, and cubic crystals on a matrix or with other minerals. The Greek word for "leaf" served as the inspiration for the mineral's name, which was given to it by R. J. Hauy in 1806. Because of its unusual propensity to collapse when heated, this term
