Quartz
Geology
Quartz is piezoelectric & accumulates an electric charge when mechanical stress is applied. Quartz oscillates at
a perfect & steady vibration this is why it is used in clocks to keep time.
Quartz (named after a Slavic word for "hard") is the most common mineral found on the surface of the Earth &
the second most abundant mineral in the Earth's continental crust, after feldspar. It is made up of a continuous
framework of SiO4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving
an overall formula SiO2. A significant component of many igneous, metamorphic & sedimentary rocks. This
natural form of silicon dioxide is found in an impressive range of varieties & colours.
Metaphysical Properties
The most powerful healing & energy amplifier on the planet because of its unique helical spiral crystalline
form. Excellent for identifying & releasing blockages. Works on all levels of self. Aids memory, absorbs,
stores, releases & regulates energy. Excellent to use for manifesting. Dissolves Karmic seeds. Enhances
psychic abilities & attunes you to your spiritual purpose. Holding quartz in your hand doubles your
biomagnetic field. Dispels static energy. Storing information like a natural computer these crystals are a
spiritual library waiting to be accessed.
Crystal Healing
Master healer, immune system, brings balance to all.

Causes of Colour:
Violet to purple (amethyst), O2+→Fe4+ charge transfer, due to irradiation.
Blue, inclusions of blue dumortierite or tourmaline.
Green ("greened amethyst" or prasiolite), Fe2+.
Green (aventurine quartz), chromian mica (fuchsite) inclusions.
Yellow to orange (citrine), O2-→Fe3+ charge transfer, various Al3+ related colour centers.
Smokey (smoky quartz), colour center related to the Al3+ impunity.
Pink (rose quartz), charge transfer between a substitutional Ti4+ and an interstitial Ti3+ unstable colour center Oion bridging between substitutional aluminum and substitutional phosphorus atom; dumortierite inclusions.
White (milky quartz), scattering of light by inclusions larger than the visible wavelengths.
