At least 8 discernable Anhydrite crystals are partly intergrown to form this large hand specimen. These crystals are generally in very good condition, though a few have flat, shiny basal faces that make me think they were cleaved (I am not certain about this, however). They reach lengths of up to 5" (12.7 cm) and have good orthorhombic prismatic form, though their faces and edges are not highly defined. All have the classic pale blue coloration and pearly luster of anhydrite, though a few faces appear to be a bit worn and dull. Each crystal is dimly to moderately translucent. There is no host rock of any sort present.
