Chlorastrolite is Michigan's state Gem
"Chlorastrolite, the official State Gem, is a mineral that is formed in association with lava flows. Its common name, “greenstone,” comes from its green color. Typical gems have a pattern of overlapping edges, ranging from yellow-green to almost black. Chlorastrolite is derived from three Latin words: “chloros,” meaning green; “aster,” meaning star; and “lithos,” meaning stone. In Michigan, chlorastrolite pebbles can be found on rocky beaches in Northern Michigan’s “copper country,” particularly on Isle Royale."- MI.Gov
