Smokey Quartz is a from of Quartz, Silicon Dioxide, and owes its color to gamma irradiation and the presence of traces of aluminum present in the earth. Energetically, it is said to be one of the most grounding & clearing stones available, both purifying & protecting. It is associated with the Root chakra (energy center). I like to think of it as a nervous system reset. Energy healers believe itto be great for anxiety & calming nerves. It can fade over long periods of time in direct sunlight.
The sphere shape is said to help emit the energy in all directions. This particular sphere is from the earth in Brazil where it was mined, cut & polished. It weighs 3.3 oz and measures about 1.75 inches in diameter.
