- Hardness. The ability to resist being scratched—or hardness—is one of the most useful properties for identifying minerals.
- Luster. Luster is how a mineral reflects light.
- Color. One of the most obvious properties of a mineral is color.
- Streak.
- Specific Gravity.

What are the 10 most common minerals on Earth?
“The Big Ten” minerals are: olivine, augite, hornblende, biotite, calcium-rich plagioclase (anorthite), sodium-rich plagioclase (albite), potassium-rich feldspar (commonly orthoclase), muscovite, quartz, and calcite.
Which mineral is green?
Chlorite. The most widespread green mineral, chlorite is rarely present by itself. In microscopic form, it gives a dull olive green color to a wide range of metamorphic rocks from slate and phyllite to schist.
What mineral is black?
Hematite. Hematite, an iron oxide, is the most common black or brownish-black mineral in sedimentary and low-grade metasedimentary rocks. It varies greatly in form and appearance, but all hematite produces a reddish streak.
Is Diamond a mineral?
diamond, a mineral composed of pure carbon. It is the hardest naturally occurring substance known; it is also the most popular gemstone. Because of their extreme hardness, diamonds have a number of important industrial applications.
What are the 8 ways to identify a mineral?
Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.

What are the different types of green minerals?
Bornite—”Peacock ore” copper mineral tarnishes a crazy blue-green. Cassiterite—Ancient and principal ore of tin. Chalcopyrite—Foremost ore of copper. Chlorite—The green mineral of many metamorphic rocks. Corundum—Natural alumina, sometimes known as sapphire and ruby. Epidote—Metamorphic mineral of a pistachio/avocado green color.
What is an example of a rock forming mineral?
Rock-forming minerals are among the most common (and least valuable) minerals in the world. They form the basis of igneous, metamorphic, and sedimentary rocks, and are used to classify and name rocks. Some examples include: Biotite—Black mica, common in igneous rocks. Calcite—The most common carbonate mineral, making up limestone.
