Apophyllite belongs to a particular class of Phyllosilicates that are a category of minerals. Formerly it was the name of a particular mineral, however, in the year 1978 it was redefined as a group of minerals that had identical chemical properties in a solid solution. These are inclusive of Apophyllite-(KOH), Apophyllite-(KF) and Apophyllite-(Naf).

This group of minerals is characteristically seen as secondary minerals found in small parts in basalt and several volcanic rocks. In the near future, there will be an alteration in its nomenclature system, which was endorsed by the International Mineralogical Association. The species were designated by eliminating the prefixes and using the suffixes

Apophyllite is weak and brittle. You should, therefore, grind it only with a 220 or 400 grit wheel. You should not grind into the grain of its cleavage. You should use only leather with Lind A or felt with Cerium Oxide for polishing. After faceting use a diamond copper lap and to cut it, and further polish it on tin with Linde A.


Apophyllite occurs in different colors, such as White, blue, colorless, reddish, Green hue and yellowish,
