In Cornwall is found this stellated and spicular variety of Sulphuret of Antimony. It seems to have the fracture which is attributed to it by most authors, and is likely to belong, as to its crystallization, to the geometrical figure beneath. It is curiously interspersed with small rhombic crystals of Carbonate of Lime. This species is sometimes of a fine polished steel lustre, and sometimes beautifully iridescent. It may easily be scraped with a knife. The powder is grey. It is easily fusible, wholly evaporating in white fumes.
