Did you know that the Greenstone is Michigan's State Gemstone?

The Michigan State Gem is commonly called "Greenstone" or "Isle Royale Greenstone". The correct mineral name is Chlorastrolite, which is a retailer 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.

Greenstone (Chlorastrolite), a variety of the mineral pumpellyite, is pretty much exclusively found along the Keweenaw Peninsula and throughout the Isle Royale archipelago -- Michigan's most remote national park.

The state legislature named chlorastrolite Michigan's official gemstone in 1973.
