Dolomite is slightly harder than calcite, scoring 3.5- 4 while calcite scores 3 on the hardness scale. If you're unfamiliar, the Mohs scale of hardness determines a stone's hardness by measuring how scratch-resistant it is. According to this scale, a stone can scratch any other mineral with a lower score.

Dolomite has a Mohs hardness of 3 1/2 to 4 and is sometimes found in rhombohedral crystals with curved faces. Dolomite produces a very weak reaction to cold, dilute …

What is Mohs Hardness Scale? The Mohs Hardness Scale is a set of ten reference minerals (numbered 1 through 10) that are used to determine the relative hardness of minerals and other objects. In this test the hardness of a mineral is defined as its "resistance to being scratched". A list of the Mohs Hardness Scale Minerals is shown in …

Dolomite is slightly harder than limestone. Limestone has a hardness of 3 on the Mohs Hardness, and dolomite has a 3.5 to 4 hardness on the Mohs scale. Even though both rocks are soluble in …

Dolomite, on the other hand, has a more laid-back kind of luster. It usually has a pearly or matte finish, which is less flashy. If calcite is like a shiny glass window, then dolomite is more like a pearl or a smooth pebble. Its luster is softer and doesn't reflect light as brightly as calcite.
