Color is the least reliable of a mineral's characteristics used in its identification.
Color is the least reliable physical property for mineral identification because many minerals can have the same color but different properties.
Sample E on the Mineral Identification Gizmo is Quartz. It has a hardness of 7 on the Mohs scale, a white streak, and breaks with a conchoidal fracture.
The color of a mineral can be influenced by various factors, such as impurities, weathering, and the presence of trace elements, making it inconsistent. Different minerals can also exhibit the same color, leading to confusion in identification. Additionally, some minerals may appear in multiple colors, further complicating their identification based solely on color. Therefore, relying on color alone can be misleading, and other tests are necessary for accurate mineral identification.
Yes, mass can help identify an unknown mineral, particularly when combined with other properties. By measuring the mass and calculating the density of the mineral, you can compare these values to known densities of minerals, aiding in identification. However, mass alone is not definitive; additional tests such as hardness, luster, and streak are also important for accurate identification.
Sample B on the Mineral Identification Gizmo is calcite.
The powder indicates the true color of the mineral and is an aid in mineral identification. That can also be called a streak.
Specimen color is the least reliable method of mineral identification. Better characteristics are streak, density, and crystal structure.

Diamond is often considered the hardest mineral in identification keys, scoring a perfect 10 on the Mohs scale of mineral hardness. Its exceptional hardness makes diamond a useful reference point for comparing the hardness of other minerals.
The mineral identification flow chart outlines a process for determining the composition of a mineral sample by first identifying its physical properties such as color, luster, hardness, and cleavage. Based on these properties, the flow chart guides the user to perform specific tests, such as acid reaction or streak test, to further narrow down the possible mineral compositions. Finally, the flow chart leads to the identification of the mineral based on its unique combination of properties.
Color is generally considered the least reliable mineral identification property because many minerals can have a variety of colors due to impurities or variations in chemical composition.
Hardness and streak color are very important. The color of the mineral helps some, as well.
