10 x 8 mm Greenstone with Pink Prehnite Pendant
10 x 8 mm Greenstone pendant with pink Prehnite in a sterling silver 4 prong setting, with 18" chain. This is a very unique stone as the coloring is very dark, with good pattern, and a nice amount of Prehnite as well, which also tells us this stone originated on the mainland of the Keweenaw.
-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 found on Isle Royale and on some of the mine waste piles of the Copper Country, although it is a rare mineral.
