Visual observation: Minerals can often be identified based on their visual properties such as color, luster (the way a mineral reflects light), crystal habit (the shape of mineral crystals), and other features visible to the naked eye. Hardness test: Hardness is a mineral’s resistance to scratching, and it can be determined using a simple scale called the Mohs
