Smoky quartz is a great crystal for grounding and for calling in Earth energy. It is also a fantastic stone for clearing negativity, or absorbing negative energy. It can help with feelings of ungroundedness, emotional upset, and difficulty in communicating. Smoky quartz is also said to provide psychic protection as well as ward off bad dreams.
This smoky quartz tower is all natural: it has not been polished or irradiated (irradiation is often used to darken the color of lighter smoky quartz or even clear quartz points, in order to give the crystal a deep smoky color). The bottom has been cut and polished so that these points do stand and display on their own.
