Pyrolusite is a manganese ore mineral and easily identifiable due to its black colour and metallic lustre, it also forms with fibrous crystals which tend to grown in a radiating fashion. However, it is fairly soft, at between 4 and 5 on the Moh's scale of hardness, it can be fiable at times and leave a black or dark grey streak. The name is derived from the Greek words for 'fire' and 'wash' which is a reference to its industrial use for removing tints from glass. It forms with associated minerals such as goethite and hematite. The colouration is striking, these particular specimens from Morocco and exhibit fibrous crystals with a radiating form on matrix, samples are available in various sizes and come supplied in a card tray with an information label.
