{{Short description|None}} Leaders of 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, history, tourism, etc. 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.

==Endnotes== {{ordered list|list_style_type=upper-alpha | {{note label|notabene_A|A|none}} In 1965, California became the first state to name an official state rock. A 2010 effort led by State Senator [[Gloria J. Romero]], a Democrat from [[Los Angeles]], sought to remove [[Serpentinite|serpentine]] from its perch as the state's official stone. Organizations such as the Asbestos Disease Awareness Organization have supported the move as the olive green rock is a source of [[chrysotile]], a form of [[asbestos]] that can cause [[mesothelioma]] and other forms of cancer. Geologists have rallied to oppose the bill, arguing that there is no way to be harmed from casual exposure to serpentine.<ref>Steinhauer, Jennifer.

The drive to name coal as an official state symbol was initiated by a high school student from [[Wharncliffe, West Virginia]], who initiated her project at a school fair and collected 2,500 signatures on a petition that was submitted to legislators.<ref>O'Caroll, Eoin.
