Benitoite is a somewhat obscure, but wonderful gemstone mineral that was only discovered in the early 1900's. 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.
