This is a large hand specimen of Angellite, the pretty blue variety of anhydrite. The color is a pale blue, and the crystals are dimly translucent. There is an appealing play-of-light from the crystal faces. While the front of the specimen is dominated by 2 large crystals (and one smaller one), the back is a jumble of dozens or hundreds of anhydrite crystals, cemented together by countless small calcite crystals (which are colorless but look white in the aggregate).
