The Michigan State Gem is commonly called "Greenstone" or "Isle Royale retailer Greenstone". The correct mineral name is Chlorastrolite, which is a variety of pumpellyite. Chlorastrolite is found chiefly as small rounded pebbles on the beaches of Isle Royale in Lake Superior and also throughout the Keweenaw Peninsula associated with the native copper deposits. The Keweenaw nuggets are found as black to green colored nodules in vesicles of the amygdaloid basalts.

Note: The Thomsonite mentioned is often proven to be mesolite or a mixture of thomsonite + mesolite, and a few were even natrolite
