A polytype of Cualstibite The original name cyanophyllite (given by K. Walenta in 1981), from the Greek for blue (κυανός) and a leaf (φύλλον), in allusion to the color and habit, was discredited in 2012 (IMA 12-B) during the definition of the hydrotalcite supergroup (Mills et al., 2012), since it was recognised as a polytype of cualstibite.

An extremely rare secondary antimony mineral closely related to zincalstibite (zinc analogue of cualstibite). Two polytypes are known, cualstibite-1T (trigonal) and cualstibite-1M (monoclinic, formerly called cyanophyllite). The latter is the more common polytype.
Dec 5, 2012 · The rare secondary mineral cyanophyllite was originally described from the famous Clara baryte and fluorite mine, Black Forest, Germany (Walenta 1981). It forms tiny greenish blue platelets, with a perfect cleavage parallel to the platy face.
