To test a mineral and its cleavage, a few essential tools are useful. A streak plate can help determine the mineral's streak color, while a hardness kit can assess its hardness using the Mohs scale. A magnifying glass or hand lens is beneficial for examining the mineral's surface and cleavage planes closely. Additionally, a hammer or geologist's pick can be used to perform a cleavage test by striking the mineral to see how it breaks along its planes.
Color, streak color, hardness, cleavage, and chemical.
By the mineral color, streak color, luster, hardness, the property of the mineral, if it's fracture or cleavage and it's specific gravity. Those are just basic, so there's many other ways to ID a mineral.
In a hand sample/specimen you can the properties used to identify minerals are luster, diaphaneity, color, streak, luminescence, play of colors, crystal shape, tenacity, cleavage, hardness, specific gravity and density, magnetism, electrical properties, reaction to acid.

Calcite is a mineral that is white or colorless and has a hardness of 2.5 and splits with cubic cleavage.
The mineral that fits this description is quartz. It has a hardness of 7 on the Mohs scale, does not show cleavage, and has a chemical composition of SiO2.

Luster refers to the way light interacts with the surface of a mineral. Cleavage is the way a mineral breaks along planes of weakness. Hardness is the resistance of a mineral to scratching. Color is the visual appearance of a mineral, which can vary widely within the same mineral species.
The five properties of a mineral include color, streak, luster, hardness, and cleavage or fracture. Color is the visual appearance of the mineral, streak is the color of the mineral's powder, luster describes how the mineral reflects light, hardness measures the mineral's resistance to scratching, and cleavage or fracture describes how the mineral breaks.
Orthoclase feldspar is 6 on the Mohs scale of mineral hardness.
Color: Observe the color of the mineral. Hardness: Use the Mohs scale to determine the mineral's hardness. Cleavage and fracture: Check how the mineral breaks. Luster: Determine if the mineral is metallic or non-metallic. Streak: Identify the color of the mineral's powdered form. Specific gravity: Measure the density of the mineral. Acid reaction: Test if the mineral reacts with acid.
The mineral might be pyrite, which has a hardness lower than calcite, a metallic luster, and cubic cleavage. Pyrite's hardness is around 6-6.5 on the Mohs scale, compared to calcite's 3. It forms cubic crystals and has a brassy color.
The properties of a mineral are primarily the result of its chemical composition and atomic structure. These factors determine characteristics such as color, hardness, cleavage, and crystal form in a mineral.
