Natural Benitoite

This rare and unusual mineral is found only in the southern part of the Mount Diablo range near the San Benito-Fresno border in California. Because of it’s similarity in color it was initially thought to be sapphire. Benitoite is unique in that it crystallizes in a class of the hexagonal system which has a trigonal axis of symmetry and a plane of symmetry at right angles to it, a class known as the dihexagonal dipyramidal. It is typically found as flattened triangular shaped crystals and in association with another rare titanium mineral, neptunite – in a matrix of white naturalite.
