Home > American Minerals IV – August 26 > MS1649 Planerite


Planerite is hydrous aluminum phosphate; it is a cation deficient member of the turquoise group. Foord & Taggart (1998) used material from this locality to redefine the species. The mineral name honors Dimitrii Ivanovich Planer (1821-1882), mineralogist and Director of the Gumeshevsk copper mines, Russia, who originally discovered the mineral (Hermann, 1862).

Planerite here forms a rather continuous coverage of pale green crystals to 0.5 mm. The planerite crystals group into wart-like aggregates. This specimen was part of the Charles Trantham (1936-2020) estate.
