They use the mineral composition, color, and texture.
It's important bcause u can classify rocks from luster and other properties.
The most commonly used chemical property to classify igneous rocks is their mineral composition, particularly the relative amounts of silica and other oxides present. Two physical properties that can help identify igneous rocks are texture (such as grain size and arrangement of crystals) and color, which can indicate the mineral content and cooling history of the rock.
Geologists classify rocks by looking at their chemical and mineralogical composition then at the the size and shape of their component minerals then at any texture, pattern or grain that the rocks may display. They also classify them in relation to how they were formed.
color for instance real gold and fools gold is the same color but 2 different rocks
pieces of rock

Scientists classify rocks based on their mineral composition, texture, and how they were formed. These classifications help geologists understand the history and properties of rocks. There are three main categories for classifying rocks: igneous, sedimentary, and metamorphic.
Rocks have a number of properties. A number of these are summarised below.Properties of rocks and rock masses:StrengthStiffnessDensityGrain / crystal sizeGrain shape (angular to rounded)Bedding thicknessJoint spacingPorosityPermeabilityChemical compositionSolubility.
In classifying rocks, there are many properties that can be useful. In my opinion, either color or texture is most useful in classifying a rock or mineral.
Geologists classify rocks based on their mineral composition, texture, and formation process. These characteristics help geologists understand the origin and history of the rocks, as well as their physical and chemical properties.
Geologists classify metamorphic rocks by the arrangements of the grains that make up the rocks.
There is a few properties that needs to be classify for seeding into groups. You will have to pick out and then group together.
This question would be too extensive to post here: Instead responding it, I recommend that you click on the link below ( Rocks and Minerals) . Thus, you'll learn everything about this subject. There are several methods of classifying, and it is not allowed to copy and paste answers here. However, to add a related link is allowed. Thank you.

by using a method which is "king Phillip came over from great Spain" this means "kingdom phylum class order family genus species"
Some basic physical properties of igneous rocks include color, texture (such as grain size and shape), density, hardness, and composition (mineral content). Additionally, features like porosity, cleavage, fracture, and luster can help further describe and classify igneous rocks.
