A rather unusual form of Muscovite, this specimen has a deep red color similar to that of Garnet. If I'm not mistaken, the color is caused by traces of cobalt. Though showing no crystal form and visible folding and creasing, it does show lots and lots of micaceous layering, and the standard, pearly luster. There are also small layers of quartz sandwiched in. This is some rather unusual material!
