Because any mineral can be any color, you cannot use color alone to identify a mineral. Color can merely help you. (Or, sometimes, confuse you!) Shape â Minerals form in certain shapes based on the elements that make them up. Some minerals, such as quartz, only form in one particular shape. Others, such as calcite, can be found in multiple shapes. Sometimes shape isnât enough and you need to use other tests to help you identify a mineral. Hardness â How hard or soft a mineral is can tell you right away what mineral it could or could not be. The hardness of minerals is based on the Mohs Hardness Scale, which ranges from 1-10, 1 being the softest and 10 the hardest.
