Mineral samples are small pieces of minerals that are collected for study and analysis. They can be found in nature or created in laboratories. Each sample has unique properties, such as color, hardness, and crystal structure, which help scientists identify and classify them. These samples are essential for various fields, including geology, mineralogy, and environmental science. By examining mineral samples, researchers can learn about the Earth's composition, the formation of rocks, and even the history of our planet. They also play a crucial role in mining and resource management.
