The Tourmaline mineral group is chemically one of the most complicated groups of Silicate minerals.  Its composition varies widely with Sodium, Calcium, Iron, Magnesium, Lithium, Aluminum, Boron and other elements.  It has a wide variety of colors including black, blue-black, brown, yellow, red, green, pink and is rarely colorless.  This mineral is found in igneous rocks, like Granite Pegmatite, and metamorphic rocks such as Schist and Marble.

Quartz is the second most common mineral in the Earth’s continental crust.  It is mainly composed of Silica or Silica based minerals.  Although Quartz is known by a variety of names, the most important distinction between types of Quartz is that of macro-crystalline, individual crystals visible to the unaided eye, and micro-crystalline, where aggregates of crystals are only visible under high magnification.  There are many forms of Quartz including Chalcedony, Amethyst, Citrine, and Carnelian which are results of mineral impurities or heat treatments.
