Yes they do
Some do and some don't - iron pyrites, gold, silver, lead ores - may have a luster. Others like bauxite (aluminum ore), pitchblende (uranium), iron ore are not lusterous.

What minerals are often present in shale?
Clay minerals, quarts, feldspar
What are the similarities metals and nonmetals have in common?
Metals and nonmetals are both in the periodic table. They both have atoms in them.
Which landform region is known as Canada's storehouse of metallic minerals?
The Canadian Shield supplies Canada with so many different minerals that it is often called "Canada's Storehouse."
What is facture of a mineral mean?
'Fracture' means 'to break'. Minerals often break (or fracture) in certain directions that many other minerals do not. The way a mineral fractures, then, helps a person narrow down the identity of the mineral. Fracture, along with color, streak color, hardness, and specific gravity are all used in the identification of minerals.
What is alloy in chemistry?
An Alloy is two metals mixed together.it is the combination of one or more elements, usually metals. the mixture of elements in an alloy gives it new properties that are different from the properties of the individual element. it often eliminates disadvantages of the pure metal .
Do minerals containing metals often have a shiny luster?

Why do metals often lose their luster?
react with the air, generally oxygen
Do minerals that contain metal often have a shiny luster?
Yes. They do.******Contrablue Adds:Unfortunately, this is often incorrect. Many metals are found in chemically "bound" form in their ores -- that is, they are in the form of salts or other compounds rather than the shiny metal. For example, copper is often found in the form of copper carbonate, which is a beautiful green mineral (pure specimens are called "malachite"). But malachite doesn't have a shiny luster because the copper is chemically bonded to oxygen and carbon!The only metals likely to be found "native" or in the uncombined, shiny state, are noble metals such as gold or platinum.The answer is True

Are minerals made up of carbon?
It depends on the definition you use. Generally, minerals are inorganic (containing no carbon), although new mineralogical classifications often include a rare group of minerals containing hydrocarbons. The unifying feature of mineral definitions is that minerals have a crystalline structure, and following this definition alone would encompass several carbon-containing compounds.
Why do metals often lose their shine and appear dull?
Most metals lose their luster when they are exposed to water because they react with the oxygen in the water and oxidize. An example is iron that reacts with the water to produce iron oxide, or rust.
How do garnets occur?
Garnet is a type of mineral that is found in nature. It is often mined from underground caves, like other minerals and metals.
Why Is Streak A Useful Property For Identifying Minerals?
The streak of a mineral is much more accurate in identifying a mineral than color. The streak of a mineral can distinguish minerals with metallic and non-metallic luster. For example, metallic minerals generally have a dark streak whereas non-metallic luster minerals often have a light colored streak.
What is the mineral with glassy luster often clean or milky white?
The mineral with glassy luster, and milky white is Quartz
What metals are ferrous metals?
Iron is often referred to as a ferrous metal, but the word ferrous really refers to compounds containing iron. Compounds containing iron having a valance of +2 are ferrous; those compounds containing iron having a valence of +3 are ferric. In a more general sense, ferrous metals are metals or metal alloys that contain the element iron. Steel, for example, is a ferrous metal, and there are a number of other alloys that contain iron. Use the link below for more information. all ferrous metals are magnetic and contaain a small amount of other metals to provide the correct properties
