Learning to identify rocks can be difficult when you are first started. Once you get the hang of it though you will start to notice patterns and similarities that will help you to identify rocks and minerals. A good way to start is by purchasing a book about rocks and minerals as well as doing some research on the web.
A crystal system is a method for categorizing minerals based on their crystal structure and symmetry. This classification is useful because it helps geologists and mineralogists identify and describe minerals more accurately. It also provides insight into the physical properties and formation conditions of minerals within each crystal system.
Specific gravity is a useful property to help identify minerals because it can provide insights into the mineral's density compared to water. By measuring the specific gravity of a mineral, geologists can narrow down potential mineral identifications based on known specific gravity values for different minerals. However, it is not always a definitive method for mineral identification and is usually used in conjunction with other tests and observations.
Physical mineralogy is the specific focus on physical attributes of minerals. Description of physical attributes is the simplest way to identify, classify, and categorize minerals, and they include:crystal structurecrystal habittwinningcleavagelusterdiaphaneitycolorstreakhardnessspecific gravity
The specific arrangement of atoms in a crystalline structure gives minerals distinct geometric shapes and properties that are unique to each mineral. By examining these properties, such as cleavage, hardness, and crystal habit, geologists can identify minerals based on their crystal structure. This allows geologists to classify and distinguish different minerals in rocks and ores.
Identifying a mineral based solely on its color is the least accurate method, as many minerals can have the same color but different properties.

Luster is not a good property for identifying minerals because many minerals look similar. Your best way of knowing which mineral is which is by measuring their hardness.
The worst way to identify a mineral is by relying solely on color or appearance, as many minerals can have similar colors or appearances despite having different chemical compositions. Additionally, using taste or smell to identify minerals is highly dangerous and not recommended. It is important to use a combination of tests such as hardness, streak, and specific gravity for accurate mineral identification.

Minerals that contain carbonate ions, such as calcite and dolomite, will effervesce or bubble when they come into contact with hydrochloric acid due to the release of carbon dioxide gas. This reaction is a simple way to identify these minerals in the field.
Color alone is not the best way to identify a mineral because many minerals have the same color or more than one color. Mineral color can be highly variable and it can change depending on surroundings.
