A classic Sussexite specimen of a light pinkish color in a mottled dark gray and off-white matrix. This large and rich example of a classic style of Sussexite has a very fine and almost chert-like (granular massive) texture to it without any distinct crystals. A card that comes with the piece indicates this piece originated from the North Ore Body; and it was collected by Richard Bostwick who was a mine manager in that specific part of the mine. Sussexite is a rare manganese borate named after the county where the Franklin Mine is located, and is also the type locality for the species. The dark pink Sussexite is intergrown with dark gray angular matrix fragments on one side and circular to elliptical orbs of the same material on the back making for nice contrasting colors and textures. The off-white veinlets are probably Calcite and the almost powdery, bright orange material is secondary Zincite. This is an excellent example of this type of Sussexite for the species and was one of the prettier examples in Bostwick's opinion, as he had it installed for decades in a special exhibition dedicated to the section of the mine in the Sterling Hill Mining Museum.
