Variations in these properties produce different kinds of lustre, whereas variations in the quantity of reflected light produce different intensities of the … Web6 de mai. de 2024 · Background. Luster is a property of the mineral response to light. When light illuminates any matter, you may see see one of several different responses. light may reflect off the surface, like from a mirror. light may reflect off the surface and be partially absorbed (penetrate) into (and perhaps through) the mineral.
