California designated serpentine the official state rock in 1965 (California was the first state to designate a state rock). All State Rocks

California has a greater number of minerals and a wider variety of rock types than does any other state. Serpentine is a shiny green and blue rock found throughout California. It contains the state's principal deposits of chromite, magnesite, and cinnabar.

Serpentinite is a rock composed of one or more serpentine group minerals, the name originating from the similarity of the texture of the rock to that of the skin of a snake. Minerals in this group are formed by serpentinization , a hydration and metamorphic transformation of ultramafic rock from the Earth's mantle .
