Quartz

Quartz (Tibet)

Quartz is the second most common mineral in the earth's crust after the feldspars and appears in its most pure and beautiful form as rock crystal. Chemically, quartz consists of very pure silicon dioxide (SiO₂) and crystallises in the hexagonal crystal family.

Fine- to medium-grained metamorphic rocks with a quartz content of 98% or more are called quartzite. They are very resistant to environmental influences.

In the human organism, quartz is particularly significant for the silicic acid process, through which the I-organisation can intervene in the nerve-sense system in a formative way. Quartz is therefore strongly connected to the human head, which is the sensory centre.
