Quartz is the most abundant and most common mineral
on the Earth. It is found in almost every geological
environment and also it is at least a component of
almost every rock type. It has a hexagonal crystal
structure and is made of trigonal crystallized silica. It is
most varied in terms of varieties, colors and forms.
The most important distinction between the types of
quartz is that one is of macrocrystalline, which is
individual crystal visible to the unaided eye, and the
other is microcrystalline or cryptodrystalline varieties,
aggregates of crystals visible only under high
magnification. Chalcedony is the generic term for
cryptocrystalline quartz. The transparent variety tends
to be macrocrystalline and the cryptocrystalline
varieties are either translucent or mostly opaque.
