| Fossil coral Lithostrotionella 4 inch wide. Fossil coral is State gem of West Virginia. The State Gem is technically not a gemstone, but rather the silicified Mississippian Fossil Coral Lithostrotionella, preserved as the siliceous mineral chalcedony. This coral and many other varieties lived about 340 million years ago, during the Mississippian Period. Corals may look like plants, but they are really animals. Lithostrotionella is found almost exclusively in the Hillsdale Limestone of Greenbrier and Pocahontas counties in the southeastern portion of the West Virginia. |
