Specimen status: Sold
A flat, translucent to opaque, and essentially colorless crystal, resembling an alien spaceship. Gray mud inclusions. The crystal shape is correct for glauberite, but when I tried dissolving one of these in water, a significant amount of insoluble residue was left. In addition, the Great Salt Lake frequently deposits gypsum crystals. Hence I believe these have some gypsum content as well. No damage.
