Found August 1999. MOB coll. According to Horváth et al (Min Rec 1990), kaersutite “is readily identifiable by its perfect prismatic cleavage and red internal reflections”. This photo attempts to show the perferct cleavage. At the top you can see that there are actually two perfect cleavages at an “amphibole angle\". The fracture “perpendicular” to these is conchoidal and very glassy. Note: Per László (private comminication March 2017), all analyzed \"kaersutite\" is actually the new species ferri-kaersutite (IMA2014-051).
