Sacred Seven Stone is a combination of seven minerals - Amethyst, Cacoxenite, Goethite, Lepidocrocite, Clear Quartz, Rutile and Smoky Quartz. It shares all the properties of each of these minerals. The crystals carry the energies of all the minerals combined, even if only part of the minerals are present. It is one of the few minerals which never needs cleansing or energizing.
 
The Sacred Seven is a "flambeau" mineral which is know to exhibit the phenomenon of St. Elmo's Fire, an ethereal auric light which has been seen due to atmospheric electricity.  It produces electro-magnetic waves providing the self-luminous quality and assists one in seeing auras and in maintaining the connection between the physical and ethereal planes.
