Comments: | From the type material description in Brush and Dana (1878): "Reddingite occurs sparingly in minute octahedral crystals; belonging to the orthorhombic system. It is also found more generally massive with granular structure; it is associated with dickinsonite, and sometimes with triploidite. As compared with the other species which have been described it is a decidedly rare mineral. The massive mineral shows a distinct cleavage in one plane...crystals are occasionally coated dark from surface alteration" Difficult to distinguish from pink hureaulite or yellowish fillowite. | |
