Benitoite is a somewhat obscure, but wonderful gemstone mineral that was only discovered at the beginning of this century. It has a sapphire blue color and was first thought to be a variety of sapphire. But x-ray studies showed that the crystal structure was unlike any mineral previously discovered. It is one of only a few minerals to crystallize in the bar 6 m 2 class called the ditrigonal-dipyramidal symmetry class. While this class is techically hexagonal, it produces trigonal (triangular) looking crystals. Additionally benitoite is also a fluorescent mineral. Nearly all specimens of benitoite will fluoresce a beautiful pale blue color under UV light." Location: Dallas Gem Mine, San Benito Co., California
