This interesting cluster of anhydrite crystals has the characteristic light blue color and soft translucency of angellite. The crystals are strongly striated, and the groves and some surfaces are fille/coated with the original dirty-white host rock. The clean faces, for the most part, appear to be basal cleavage, except that they are all curved surfaces. Through these faces, one can see that the angellite is actually transparent but is nearly filled with minute milky inclusions.
