Interlocking platy 'books' of micaceous Zinnwaldite crystals with an extensive unidentified orange coating form the matrix hosting a cluster of dark grey to black intergrown, somewhat pyramidal, Cassiterite crystals, the largest crystal reaching 1 cm across. The Cassiterite displays an unusual matt, to silky surface lustre. Further, scattered, small (1 to 2 mm) cubic crystals of very dark purple Fluorite are also present. The main Cassiterite crystal is completely undamaged, but the others are either slightly chipped or, in the case of a second grouping, has an edge missing where it is fractured. This is, nevertheless, a nice classic association of species from the famous Horní Slavkov (Schlaggenwald) area in Karlovy Vary Region, Bohemia, Czechia.
