Scintillating, hexgonal, black to gemmy golden-yellow wurtzite prisms in parallel-growth richly cover the undulating matrix of massive sulfides. Wurtzite is an uncommon zinc, iron sulfide, a polymorph of sphalerite and is seldom found in well-developed crystals worldwide. Wurtzite is usually found as crusts or blebs, so this is outstanding material. Classic material from the famous and ancient Les Malines Mine of Gard, France and according to the label was collected in 1992. Ex. Wes Parker Collection.
