States in the U.S. which have significant mineral deposits often create a state mineral, rock, stone or gemstone to promote interest in their natural resources. Not every state has an official state mineral, rock, stone and/or gemstone, however.
In the chart below, a year which is listed within parentheses represents the year during which that mineral, rock, stone or gemstone was officially adopted as a State symbol or emblem.

Did you know
California was the first state to designate an official State Rock. Colorado is the only state whose geological symbols reflect the national flag's colors of red (rhodochrosite), white (yule marble), and blue (aquamarine). Massachusetts also has a State Historical Rock (Plymouth Rock), State Explorer Rock (Dighton Rock), and State Building and Monument Stone (Granite).
