It is made up of a lattice of silica (SiO2) tetrahedra and has a hardness of 7 on the Moh's scale. Quartz goes by an array of different names. The most important distinction between types of Quartz is that of macrocrystalline (individual crystals visible to the unaided eye) and the microcrystalline or cryptocrystalline varieties (aggregates of crystals visible only under high magnification), often referred to as "Chalcedony". Snow Quartz (also called "Milky Quartz", "Quartzite" or "White Jade") is the second most common variety of Quartz. This fresh, icy-white gemstone gets its appearance from inclusions of tiny gas bubbles and/or water. Snow Quartz is said to bring good fortune, and is a calming and soothing gemstone. Many believe it to be helpful for meditation and looking within. It is also considered beneficial for the immune system.
