This unusual pseudo features a diverging, half moon spray of dark gray, laumontite crystals which has been totally replaced by quartz colored brown by inclusions of (i am told) delessite. The crystals average 3.0 cm in length. It is overall very elegant and interesting, and is complete on both sides and very 3-dimensional. I have seen some of these clusters of similar style labeled as pseudo after anhydrite but the color was different, and the robustness and weight slightly different, so I am inclined to believe this identification after laumontite to be valid.
