DescriptionDEVILLINE (not ROSASITE)
Bou Beker (Bou Becker), Touissit, Touissit District, Oujda-Angad Province, Oriental Region, Morocco
One of the advantages of hindsight is that some mysteries tend to get cleared up with the help of time. Recently, the material identified as "Rosasite" in the documentation that is part of this lot, turned out to be a Calcium Copper Sulfate: Devilline. The Bou Beker Devilline is always overcoated by the Selenite variety of Gypsum, giving the Devilline an ice-covered appearance. Here, approximately 50 "ice-berries" of this mineral pair can be found, on two of the three sides of a wedge of non-descript Calcite. Individual "berries" measure up to .56 inch (1.4 cm) and all are in excellent condition. There are traces of a deep blue mineral under the Selenite as well, presumably Azurite.
Overall measurements: 6 x 3 x 2 inches (15.2 x 7.6 x 5.1 cm).
Provenance: Keith Proctor [Hoppel # D1596]
