== Etymology== Kruťaite was first discovered in Petrovice in Okres Žďár nad Sázavou, Czech Republic and described in 1972 by Zdenek Johan, Paul Picot, Roland Pierrot and Milan Kvaček. It was named after Tomáš Kruťa (1906–1998), a Czech mineralogist and director of the mineralogical laboratory of the Moravian museum.
