Identification in the Field and Classroom. Dolomite is slightly harder than limestone. Dolomite has a Mohs hardness of 3.5 to 4, and limestone (composed of the mineral calcite) has a hardness of 3.
Dolomite properties are very similar to Calcite. Dolomite may also be coarse to fine granular, massive or fibrous crystalline habits.
However, transparent clear Dolomite is indistinguishable from Calcite unless complicated optical tests are performed. Quartz - Much harder (7).
