Luster is the way a surface reflects light. Luster appears in minerals like when minerals are shiny or dull looking. When you say that you mean the way light reflects off the surface. Minerals can have metallic, submetallic, and nonmetallic luster. If a mineral were dull its luster would either be a submetallic or a nonmetallic luster. But if a mineral were shiny its luster would be metallic. Opals luster is a greasy looking reflection. Itâs not quite shiny but it has a greasy looking luster. In order to find a mineralâs streak what you do is the mineral has to be rubbed against a piece of unglazed porcelain or streak plate. When you do this the powder from the mineral ends up on the streak plate.
