List of U.S. state minerals, rocks, stones and gemstones

{{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 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.

West Virginia joined Kentucky and Utah, which also recognize coal as a state mineral or rock. 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.
