This rather intriguing specimen consists of a crust of massive-to-crystalline Chabazite that was separated from its base rock. The areas that bear crystals show trigonal bladed, "spearhead" crystals with a diamond-shaped cross-section. The largest of these do not exceed 0.4" (1.0 cm) in length. Though some of them are obviously broken, most are in excellent condition besides their apparent weathering. They all have a very pale blue-violet coloration and appear to be dirty, though their discoloration is likely caused by a coating of another mineral. Their worn state is shown also through their dull, almost matte luster, which is offset by the brighter, pearly luster of the breakage surfaces. All are at least translucent; though some may be even transparent, their dull luster prevents me from being sure. There is also a bit of rust-staining on the specimen.
