Diaspore is not a mica, but exhibits what some might think is a micaceous habit. Much like this specimen, Diaspore will have elongated plates, may be foliated, scaly with a perfect cleavage. It can occur with magnetite, corundum, spinel, chlorite, dolomite in metamorphic limestines or chlorite schists (Encycl. of Min.)
