Mineral Colour Plates are small thumbnail images of minerals, as well as synthetic compounds and chemical elements, with articles that can be found in the MIROFOSS database. The following table shows all of the HEXAGONAL CRYSTAL minerals found in MIROFOSS organized vertically by mineral group. Clicking on a mineral plate image will bring you to the corresponding MIROFOSS article. Please note this page may take a while to load on slower computers or with slower internet connections.

In crystallography, the hexagonal crystal family is one of the six crystal families. In the hexagonal family, the crystal is conventionally described by a right rhombic prism unit cell with two equal axes (a by a), an included angle of 120° (γ) and a height (c, which can be different from a) perpendicular to the two base axes. The hexagonal crystal family consists of the twelve point groups such that at least one of their space groups has the hexagonal lattice as underlying lattice, and is the union of the hexagonal crystal system and the trigonal crystal system. There are 52 space groups associated with it, which are exactly those whose Bravais lattice is either hexagonal or rhombohedral.
