A luster test is used to determine the appearance of a mineral's surface shine or reflectivity. It involves observing how light interacts with the mineral's surface to categorize its luster as metallic, submetallic, vitreous, pearly, adamantine, silky, or resinous. This test can be helpful in identifying minerals.

Yes, shiny minerals have a metallic luster due to the way light is reflected off their surfaces. This luster is a physical property of minerals, indicating their metallic appearance. Examples of minerals with metallic luster include pyrite, galena, and hematite.
Luster = how much the mineral reflects light, so yes, all would have luster, but some are metallic and some are non-metallic
No, not all minerals have a glassy luster. Minerals can display a variety of lusters, including metallic, dull, pearly, and waxy, depending on their composition and crystal structure.
Metallic luster: minerals that have the appearance of polished metal, such as pyrite or galena. Vitreous luster: minerals that have a glassy appearance, like quartz or feldspar. Pearly luster: minerals that exhibit a soft, pearl-like sheen, such as talc or gypsum.
A mineral's ability to reflect light is a test for its luster. Luster describes how light is reflected off the surface of a mineral, and it can be classified as metallic or non-metallic. Metallic luster is shiny like metal, while non-metallic luster can be categorized further into subcategories like vitreous (glassy), pearly, or dull.
You would need to look at the individual minerals. A rock does not have a luster.
