The sister to Smokey Quartz goes by Morion - the original term which the druids gave to this beautiful crystal. . .
As one of the most potent crystals for metaphysical arts practitioners, Morion can effectively remove negative spirits or energies from the auric fields through the use of grounding techniques or by placing directly on the body.
Like many crystals with darker hues, it has an essential role in spiritual practices throughout history. It was used for similar purposes by placing it outside of houses or in windows to prevent drifting spirits from entering a family’s space. . .
They are useful in shadow work, helping to face the dark aspects of self and to release obstacles. They are grounding and aid in coping with grief. Morion can be used to bring connection with the "darker" faces of the deity, such as the Crone and Hunter archetypes. A stone that holds an open connection with Spirit and your Guides and can help bring them a bit closer for guidance and comfort.
