Pale green diaspore crystals occur together with white natrolite in a characteristic mineral association from the Saga 2 Quarry near Sagåsen, Norway. The pale natrolite clearly highlights the greenish diaspore areas and gives the specimen a contrasting structure.
Diaspore belongs to the aluminum hydroxides and is particularly interesting for systematic mineral collections. Its association with natrolite represents a typical mineral assemblage from the complex alkaline rocks and pegmatites of the Langesundsfjord area.
