Its simple, see a lot of people would have guessed a geode is a mineral or a gem. But its not. Geode is a sedimentary rock so instead of looking for the luster steak and hardness look facts on it like from its sedimentary form. A geode might have minerals in it, but that doesn't make it a mineral itself.

If a mineral has no streak is it metallic?
When identifying minerals, having no streak is a property of hardness. A streak plate has a hardness of ~7(Moh's Scale). Thus any mineral having a hardness greater than 7 will have no streak.Metallic is the description of luster. Or the general appearance of a mineral surface in reflected light.If you were refering to the mineral having metal elements in it, streak is actually very useful for identifying them. Many minerals that are composed of non-metals have a white streak which can appear to be no streak, however there are also many minerals with no streak which are composed of non-metallic minerals (Diamond).
What are the 5 characteristics for a mineral?
1.Color 2.Luster 3.Crystal Shape 4.Flourscent 5.Hardness 6.Density
How do you identify all the properties scientists use to classify minerals?
Scientists classify minerals based on properties such as color, streak, luster, cleavage, fracture, hardness, density, and crystal habit. By observing these properties, scientists can determine the identity of a mineral and place it into the appropriate mineral group.
What is the hardness luster and streak color of shale?
== == Depends upon the composition of the conglomerate, which can be anything. This is not a normal thing to do for a sedimentary rock. Hardness, luster, and streak are used to aid in the identification of minerals. Conglomerate is a rock composed of other rocks which could contain a wide variety of minerals.
What five characteristics do geologists use to identify a mineral?
Geologists use properties such as color, luster, hardness, cleavage, and specific gravity to identify minerals. These characteristics help in distinguishing one mineral from another based on their physical and chemical properties.

What is the hardness luster and streak color of a diamond?
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.
What are the four properties of minerals?
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.

What is the streak luster hardness and crystal system of petroleum?
Petroleum is a liquid mixture of hydrocarbons. It does not have a streak luster, hardness, or crystal system as it is not a mineral but rather a naturally occurring substance derived from organic matter.
What properties are used to identify rocks and minerals?
Hardness, Cleavage, Luster, Color, Streak, and Texture.
