Idaho Gems

Idaho has been nicknamed the Gem State since territorial days. Over 240 different minerals have been identified in Idaho. The state can claim world-class specimens of Vivianite, Pyromorphite, Cerussite, Smoky Quartz, Aquamarine, Ilvaite and other minerals. Many of these specimens are rare and cherished exclusively in museums, private collections and gem dealers. One exception to this limited availability is the Star Garnet, the official state gem. This beautiful stone is found in some abundance only in Idaho and India.
