California State Gemstones

    State Gemstone: Benitoite
    Benitoite is a rare blue stone named after where it was found, the San Benito River. It was officially adopted as the State Gemstone in 1985.

    State Mineral: Gold

    Much of California's history revolves around gold. So, it is not much of a surprise that California's state mineral is gold. It was officially adopted as the State Mineral in 1965.

    State Rock: Serpentine

    Serpentine was adopted as the official State Rock in 1965. Occassionally, gemstone dealers will try to pass serpentine off as Jade since it is a green non-translucent stone. Serpentine is a much softer stone and scratches easily.
