OFFICIAL MINERALS, GEMSTONES, & ROCKS
OF THE U.S.A. STATES

Below is a list of the official minerals, gemstones, and rocks of the various U.S.A. states. Eleven states have all three; five states have none. Twelve states have only an official gemstone, two states have only a rock, two more only a mineral. Of course, the members of the various state legislatures don't feel constrained to using actual minerals, gemstones, and rocks, let alone use them correctly, so the following entries are somewhat arbitrary and inconsistent. It's almost like one state senator said, "It's not a gemstone," but another replied, "If petrified wood is good enough for my bolo, it's good enough to be our state gemstone."
