Fact sheet
Description: 

Diaspore is found as a hydrothermal mineral in some alkalic syenite pegmatites, such as this one from Saga Quarry, Sagåsen in Norway. Note the subtle lilac colour in some crystals of diaspore in PPL. Here it is associated with natrolite.

Rotation 1 - diaspore AlO(OH)

Rotation 2 - natrolite Na2(Si3Al2)O10•2H2O
