The luster scale is a measure of how light is reflected off the surface of a mineral. It describes the appearance of a mineral's surface based on its shininess or dullness. There are different categories of luster, such as metallic, vitreous (glassy), pearly, and dull.
Nope. It is actually the hardness. I'v been trying to find out what the Luster scale is myself....:S
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.
Mica has a vitreous to pearly luster, which means it appears shiny like glass and has a somewhat reflective quality due to its layered structure. This luster is caused by the reflection of light off the mineral's smooth, flat surfaces.
A diamond is the hardest natural substance, scoring a 10 on the Mohs scale. It has a brilliant luster due to its high refractive index. The streak color of a diamond is colorless, as it does not leave a streak on a streak plate.
the color of the mineral beryl can change, depending on the sample

No, just the hardness.
Luster is simply a way of describing how a mineral reflects light. No minerals absorb 100% of light, so all minerals have some degree of 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.

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

it has a metallic luster it is shiny and gray it place on the mohs scale is 2.5 its gravity is 7.5 its texture is hard
"Tuff", a rock made up of volcanic ash and other things, is not a mineral, so it has no hardness index or luster.
A diamond is the hardest natural substance, scoring a 10 on the Mohs scale. It has a brilliant luster due to its high refractive index. The streak color of a diamond is colorless, as it does not leave a streak on a streak plate.
Yellow, shiny. I don't believe there is a numerical luster scale, just on ordinal one. gold can be polished to as good a reflective surface as any other metal (but some wavelengths will be absorbed thus its yellow color)
Diamonds do not have a metallic luster; diamond luster is adamantine to waxy.
