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."
