System:TriclinicColour:Generally colorless, may ...
Lustre:VitreousHardness:1 - 2
Member of:Laueite Group
Name:Named in 1999 by Jochen Schlüter, Karl-Heinz Klaska, Karsten (Carsten) Friese, and Gunadi Adiwidjaja after Jürgen Kastning (b. 1932), from Reinbeck near Hamburg, Germany, mineral collector and mineral dealer specializing in phosphate minerals, who discovered the mineral.
Dimorph of:Mangangordonite


Commonly found in euhedral crystals. Crystals are generally transparent to white. The habit is frequently thin bladed with an acutely, steeply sloping end. Length of an individual crystal rarely reaches 1 mm in size.
