The old label on this specimen claimed this to be Otavite. It's was a possibility since the Otavite does occur on Cerussite and the crystals are similar not to mention that both are carbonates. Well, not so. This is a specimen of Cerussite with crystals 1.5cm across. The entire specimen is coated with white, rhombic micro crystals of Dolomite. It was tested. Nonetheless, still a good specimen.

A very rich specimen loaded with 1-2mm bladed and prismatic crystals of Scholzite (stubby prismatic with nearly square cross-sections) and Parascholzite (long, prismatic, more bladed). These descriptions are very generalized, but are based on photos from two books: "Hagendorf" by J. Kastning and J. Schluter and "Palermo" by Whitmore and Lawrence.  The descriptions on Mindat more or less follow these descriptions. At the Tip Top mine, Parascholzite crystals are also long and bladed. Having said that, the specimen should be analyzed (XRD) to determine which is which.
