Pure antimony is silvery gray and metalliclooking. If antimony is melted and then allowed to crystallize, it manifests a characteristic pattern known as the star of antimony.
The Sulfide Class minerals comprise an economically important class of minerals. Most major ores of important metals such as copper, lead and silver are sulfides. Strong generalities exist in this class. The majority of sulfides are metallic, opaque, generally sectile, soft to average in hardness and they have high densities, black or dark-colored streaks, and an igneous origin.
