"Tuff", a rock made up of volcanic ash and other things, is not a mineral, so it has no hardness index or luster.
Arkose typically has a luster ranging from dull to earthy due to its composition of quartz, feldspar, and other minerals. On the Mohs scale of hardness, arkose has a hardness of around 6-7, depending on the specific mineral content and composition.
Diamond is a familiar mineral that exhibits adamantine luster. Its exceptional hardness and perfect cleavage contribute to this distinctive luster, giving it a brilliant shine and sparkle.
Magnatite is the mineral that has a nonmatallic luster, is black, and can be scratched by a fingernail.

Luster refers to the way light interacts with the surface of a mineral. Cleavage is the way a mineral breaks along planes of weakness. Hardness is the resistance of a mineral to scratching. Color is the visual appearance of a mineral, which can vary widely within the same mineral species.
limestone's hardness is 3-4 and it does not have a luster it's main constituent is the mineral calcite, and has a vitreous or glass luster.

Nope. It is actually the hardness. I'v been trying to find out what the Luster scale is myself....:S
The luster of tuff rock is typically dull to earthy due to its composition of consolidated volcanic ash and fragments. It does not exhibit a shiny or reflective surface like some other types of rocks or minerals.

Plutonium is a silvery metal.- Vickers hardness: 255 - Brinell hardness: 242 - Mohs hardness: cca. 3,7
The four properties of minerals are color, streak, hardness, and luster. Color refers to the outward appearance, streak is the color of a mineral when it's powdered, hardness is the resistance to scratching, and luster describes the way light reflects off the surface of a mineral.

You can use hardness(Moh's Hardness Scale), luster, shape, and fracture to identify quartz.
