Overview:Benitoite is a rare blue stone named after where it was found, the San Benito River. Benitoite is a rare gem that was first discovered in 1906 along the headwaters of the San Benito River in San Benito County, California. It was officially adopted as the California State Gemstone in 1985. Benitoite has a very unusual crystalline shape. It is the only known ditrigonal-dipyramidal crystal. Its sapphire-blue color is unusual, but it really comes out in ultraviolet light, where it shines with a bright blue fluorescence.
It has high dispersion and is very sparkly. Helps to
make one more in tune with positive ecological principles.
