| − | [[Mineral]] [[crystals]] come in a seemingly infinite range of shapes. But behind this tremendous diversity of form there is a strict order, because crystals always grow according to simple [[mathematical]] laws.

These are called [[isometric]], [[tetragonal]], [[hexagonal]], [[orthorhombic]], [[monoclinic]], and [[triclinic]]. Chesterman, p. 33 | + | #REDIRECT [[Crystal system]] |
