Smokey Quartz is a variety of Quartz that has been naturally irradiated to produce a transparent "smokey" brown coloured crystal ranging from pale to deep in its intensity. It can also be irradiated by "man", the process of which generally results in a much deeper and darker colour intensity.
The frequency of Smokey Quartz is connected to the base and Earth Star chakras aiding in the stabilization of the physical body and grounding high vibrational energy to the magnetic core of the Earth.
Smokey Quartz will absorb and then transmute any negative energies present in one's energy fields or one's environment making Smokey Quartz a crystal for both psychic and environmental protection.
