Apophyllite
Apophyllite is a hydrated silicate of calcium and potassium, KCa4Si8O20 (OH, F) .8H2O. They form columnar crystals terminated by dipyramidal surfaces. It occurs in the cavities of volcanic rocks, where it forms beautiful drusen. It also rarely occurs in skarns, pegmatites, veins of alpine paragenesis, etc.
