Light (sunlight) irradiated mineral surface, the light was scattered, the internal reflection or in the uneven surface of a special luster. Grease Gloss: Glossy minerals, due to scattering causes the surface to reflect the ability to reflect the light, the surface like a layer of oil coated like wax, quartz. Pearlescent luster: luster like rosin-like, in the darker minerals, such as the yellow brown sphalerite, cadmium sphalerite at the fracture of the Department of luster, with a diamond luster mineral fracture at the luster. Asphalt luster: standard gloss as bituminous minerals, mostly appear in the black semi-metallic luster minerals.Vetrosa

Pearl luster: standard luster as clam inside the flash halo color, with a complete cleavage of transparent minerals, such as pearls, muscovite, through gypsum. Silk gloss: Crystalline fibrous flaky aggregates of transparent minerals, such as silk-like, is a glass luster variant, such as fiber gypsum, sericite, asbestos. Waxy luster: luster as candle surface, mostly appear in the cryptocrystalline, microscopic particles, colloidal minerals, is a glass luster variants, such as pyrophyllite, serpentine, chalcedony, opal. Soil luster: appear in loose, porous, finely divided minerals, is a glass luster variant, such as kaolin, bentonite, diatomaceous earth. Dark luster: appear in the dark soil minerals, bleak, such as manganese soil, cobalt ore, hard manganese ore, soft manganese ore.Vetrosa
