Dolomite is also slightly harder, denser and never forms scalenohedrons (calcite's most typical habit). Dolomite differs from calcite, CaCO3, in the addition of magnesium ions to make the formula, CaMg(CO3)2. The magnesium ions are not the same size as calcium and the two ions seem incompatible in the same layer.
