FNC-4L0Gypsum

Bou Beker, Touissit-Bou Beker District, Jerada Province, L'oriental Region, Morocco

Dimensions: 11 cm x 15 cm x 4 cm

A very fine gypsum cluster growing on dolomite.
I don't know if you can consider this to be a single crystal or a cluster.
Apparently these kind of forms can easily be bent when wet to increase the curvature of the crystal.
