Aug 27, 2019 · Calcite also forms flat, rhomboid “poker chip” crystals, but dolomite does not. Calcite responds vigorously to acid, while dolomite responds less vigorously. Calcite is 3 on the Mohs Scale of Hardness, but dolomite is only Mohs 4-4.5. One other difference you may see is the smoothness of the crystal faces on your specimen. Dolomite has a Mohs hardness of 3.5, which is slightly harder than calcite. Dolomite also etches more slowly than calcite, but it will still etch. Example: Super White a well known dolomitic marble that is frequently mislabeled as quartzite. Superpower: Proximity to dolomite strengthens teeth and makes dental visits less stressful.Figure 4.6.5 4.6. 5: Some minerals have different streaks than their visual color.
