These minerals are defined to have precicely these hardnesses. Other minerals are equal to these values ONLY IF the index mineral can scratch the test sample and the test sample can scratch the index mineral. If a mineral has a hardness between two of these index minerals, it may be reported as between two values, such as hardness 4-5.
