4E13: Spheroidal Pyrolusite aggregates on a limonite matrix as bundles of crystals with finely but deeply striated faces, of considerable size and an extraordinarily bright luster contrasting with Romanéchite aggregates, which are powdery with a deep black color. The specimen is of an extraordinary quality for the locality and even for the species.
