hexagonal pseudomorphs after aragonite-2
These apparently hexagonal plates originally started out as complex twins of
aragonite crystals, but have since been converted to calcite.  The re-entrant angles
on some of the hexagonal sides show that the original crystals were really not a
hexagonal mineral.
