Hexagonal polytype with a hexagonal and a trigonal
polytype growing on the pedion of an intermediate crystal.
886. Tiny sphalerite epitaxic on trigonal wurtzite.
883. Very thin sphalerite? crystallites arranged
in an almost fractal pattern.
874. Gemmy hexagonal wurtzite growing out
of a crack.
868. Highly elongated wurtzite showing morphological
changes during growth, perhaps coinciding with polytype changes.
