About the stone

Benitoite is a rare, usually sapphire-blue barium titanium silicate prized for its brilliance. Prospector James M. Couch is generally credited with its discovery in California’s San Benito Mountains in 1907; mineralogist George D. Louderback identified it as a new mineral that year and named it after its locality. San Benito County remains its principal source of gem-quality material, although small occurrences are known in Japan, Australia, and Arkansas; it became California’s official state gemstone in 1985. Its lore centers more on its discovery story than ancient tradition: initially mistaken for sapphire, it earned the romantic nickname “California blue diamond,” though it is neither sapphire nor diamond.

Care and handling

Benitoite is fairly durable at 6 to 6.5 but can chip, so avoid hard knocks. Clean with lukewarm water, mild soap and a soft cloth; avoid steam, ultrasonic cleaners and sudden temperature changes. Do not look at ultraviolet light sources directly when viewing its glow, and use a proper UV lamp safely.

Individual experiences with Benitoite vary, and its effects are personal rather than guaranteed. Cherish it as a rare gem, and seek qualified professionals for any health concern.
