The Seven Crystal Systems The shape of the lattice determines not only which crystal system the stone belongs to but all of its physical properties and appearance In some crystal healing practices the axial symmetry of a crystal is Octahedron diamond fluorite magnetite

Crystal System Isometric Member of Hematite A ferromagnetic iron oxide which may therefore be confused with magnetite Maghemite is formed by weathering or low-temperature oxidation of spinels containing ferrous iron commonly magnetite or titanian magnetite It is a widespread yellow pigment in continental sediments rocks and soils

Bauxite is the principal ore of aluminum The first step in producing aluminum is to crush the bauxite and purify it using the Bayer Process In the Bayer Process the bauxite is washed in a hot solution of sodium hydroxide which leaches aluminum from the bauxite

Magnetite and magnesioferrite are strongly magnetic and were common components of lodestone Most minerals of the magnetite series show octahedral crystal growth habit with square or triangular sections but they may also exist as anhedral granular forms
