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.
This gorgeous crystal is from Brazil, where it was dug up from the earth. It weighs 1lb 2oz and measures about 3.75 x 2.5 x 2.25 inches. I love its dark color, the small crystal growing on the base and the texture on the back side, see video.
