Indialith "flower"

This is what the cerasite ("cherry blossom stones") look like before their typical alteration to mica: a glassy intergrowth of indialite (dark, crudely hexagonal center of the "flower") and cordierite (the bright reflections from the "flower petals"). If you squint at the picture, you can imagine the classic "cherry blossom" cerasite shape, which becomes more easily visible after hydrothermal alteration to mica. The outer zone is already partially altered to dark greenish mica; Many "systematik" species collections around the world have nondescript glassy grains of alleged "indialite" from this locality, but unless the material has this crude "cherry blossom" shape it is likely just a grain of quartz or cordierite with no indialite being present; Field of view 1cm
