Full Size ImagePlaque about Benitoite.  
Benitoite was discovered on February 22, 1907 by James Marshall Couch while prospecting for quicksilver on a fifty dollar grubstake for shares from R. W. Dallas and Tom Sanders. On July 30, 1907, mineralogy professor George D. Louderback identified it as a new mineral species, Barium Titanium Silicate (BaTiSi3O9). He named it Benitoite after the river, county and nearby mountain range. The gem-quality crystal combines the color of a sapphire with the fire of a diamond. It looks like two studdy triangular pyramids attached at their bases; its shape is unique. It flouresces a bright deep-sky blue under ultraviolet light. Benitoite in gem quality occurs nowhere else in the world. It is assopciated with other rare minerals such as Fresnoite, Joaquinite, Natrolite, and Neptunite. They formed in fractures of a serpentine rock from hydrothermal solutions. Just how such solutions occurred and what other conditions caused the crystallization of these rare minerals is still not well understood. Benitoite was declared the official California state gem on October 1, 1985.
