Greenstone -- Michigan's state gem, the greenstone, was formed in gas bubbles within basalt. Basalt is a volcanic rock, formed in Michigan in part during the Midcontinent Rift approximately one billion years ago. As the Earth's crust separated, magma welled up from beneath the crust. Rocks formed from this magma gave Michigan its valuable deposits of copper and silver -- and its state gem.
