Clear Quartz Crystal – Associated with the Crown Chakra.

The word “quartz” comes from the Greek word  “Krustalas” which means frozen ice.  The crystal can be found in many passage tombs in Europe. In prehistoric Ireland it was used for stone tools, the Irish word for quartz is grain clock meaning “stone of the sun”. This stone has been valued by many civilisations as far back as Atlantis and the Egyptians.

Clear Quartz Crystal is the second most abundant mineral in the earth’s crust after fieldspar.It is composed of a framework of silicon-oxygen tetrahedral with each oxygen being shared between two tetrahedral.

Clear Quartz Crystal belongs to the trigonal formation system. An ideal crystal shape is six sided prism terminating with six sided prisms at each end. Nicolas Stenos study of quartz revealed quartz crystals size and shape to have long prism faces always joined at a perfect 60 degree angle.

Well-formed crystals usually form in a bed with unconstrained growth. Doubly terminated crystals forms occur where they develop freely without attachment.

A geode is such a situation where the void is approximately spherical in shape, lined with a bed of crystals pointing inward.

Clear Quartz crystals have piezoelectric properties; they develop an electric potential upon the application of mechanical stress.

Not all varieties of quartz are naturally occurring, some can be treated used heat or gamma-irradiation to induce colour.
