Formula:
(Mn2+,Fe2+,Mg)Al2(PO4)2(OH)2 · 8H2O
Colour:
Generally colorless, may be white
Lustre:
Vitreous
Hardness:
1 - 2
Specific Gravity:
2.35
Crystal System:
Triclinic
Name:
Named in 1999 by Jochen Schlüter, Karl-Heinz Klaska, Karsten (Carsten) Friese, and Gunadi Adiwidjaja after Jürgen Kastning (1932 - 5 January 2017), from Reinbeck near Hamburg, Germany, mineral collector and mineral dealer specializing in phosphate minerals, who discovered the mineral.
Dimorph of:
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.
