Graphite is rather common mineral, but fine crystals are rare. Most Graphite mining areas produce enormous quantities from a single or several large Graphite veins, but collector specimens in good crystals are not commonly encountered. Much care should be given to Graphite specimens, especially thin crystals, which are fragile.
Graphite is a naturally occurring form of crystalline carbon. It is a native element mineral found in metamorphic and igneous rocks. Graphite is a mineral of extremes. It is extremely soft, cleaves with light pressure, and has a very low specific gravity.

Many different mineral commodities are important to modern society. However, when mineralogists think about mining, they are generally thinking of ore minerals that are the sources of important metals, or of minerals that have specific, highly valued properties e.g., asbestos, micas, potash, and gems of all sorts.That is what we will focus on in most of the rest of this chapter.
