Fresh and old as‐grown {001} surfaces of α‐HgI 2 platelets were studied by optical microscopy. The presence of growth hillocks and the high value of the surface entropy factor are proofs of the spiral growth of platelets. In air surfaces became gradually dull. Consequently, the final micromorphology of HgI 2 is the result of both growth (primary) and post‐growth (secondary) processes. For the revelation of defects a new, reliable etchant was used.
