Also called Amphibole Quartz, this quartz was formed with molten iron that did not form a coating, as is usual with these stones, but remained in flux and grew with the crystal. It stayed in the flow of growth if you will. It is crystalized flow.
Both the quartz and the iron are conductors of electricity. Power flows to and through them as they conduct the energy of the Earth into those places within you that feel out of touch with everything. What I know about this stone is, if you want something to happen NOW, use it. It is a crystal to assist with getting unstuck.
