Minerals owe their colors to the elements that comprise them, or from impurities that make their way into the crystal lattice. Occasionally their color is derived from the effects of proximity to radioactive elements. Crystals are divided into six different classes. Every mineral will form crystals that occur in one of these six classes. The geometric shapes that comprise these different classes of crystals occur because of the preferred arrangement of atoms within the lattice framework of any particular mineral crystal.
