-Chlorastrolite (Greenstone) is the "official state gem" of Michigan. It is a variety of the mineral pumpellyite and is found chiefly as a small, green, rounded beach pebble, showing a turtleback pattern. Greenstones can still be seen on Isle Royale and found on some of the mine waste piles of the Copper Country, although it is a rare mineral.
