This hand specimen consists of at least 2 intersecting sprays of intergrown Anhydrite blades. The blades reach a maximum length of 5.4" (13.7 cm) and are so intergrown that it is difficult to determine their other dimensions. They are all in excellent condition, however, as they show almost no fresh damage. Their orthorhombic prismatic form is also excellent- even with their intergrowth, the crystals show very well-defined edges and clean faces that possess the nearly silky luster that is standard for this species. They also have the obligatory pale sky-blue coloration and cloudy translucence. Several very small calcite scalenohedrons are scattered on the Anhydrites- they are slightly rounded, but still show good form. There is no host rock present, of course.
