Red Phantom Quartz crystals are formed when deposits of iron oxide coat the outside of the quartz crystal point. Then over the life of the quartz point another layer of quartz grows over the iron oxide layer completely enclosing the iron mineral within. Thus a phantom layer of the iron oxide resides within the quartz crystal point. When viewed from the side, it appears that a red crystal point has grown inside the larger quartz point. Hematoid Quartz is the name given to Quartz crystals included with Hematite. Often the inclusions appear as tiny reddish brown or black 'stars' or clouds within the termination end of a Quartz point. Hematoid Quartz is also known as Specularite Quartz. Red Phantom Crystals are Quartz (silica dioxide) that contain Iron Oxides, such as Hematite, represented as the chemical composition SiO2 + Fe2O3. The hardness of the structure of crystals varies with Hematite - 5.5-6.5 on the Mohs scale and Quartz rating as a 7. Chemical Composition: (SiO2) with Hematite, Goethite or Limonite inclusions; Color: Brown, Combination, Red, Yellow, Rose; (The above information is provided solely for informational purpose.
