Pure calcite is transparent and colorless but also occurs in white, gray, yellow, orange, red, brown, black, or rarely, also blue. Calcite defines the hardness 3 on Moh's scale with specific gravity 2.71 g/cm 3. It has vitreous luster and perfect cleavage in three dimensions.Physical Properties of Marble. Colour: White, pink. Derived: Limestone, dolomite. Grain size – medium grained; can see interlocking calcite crystals with the naked eye. Hardness – hard, although component mineral is soft (calcite is 3 on Moh’s scale of hardness) Structure: Massive. Group: Metamorphic Rocks.

In general, schist is made from platy minerals like biotite, muscovite, chlorite, graphite, and talc. Smaller amounts of bulky minerals like quartz and feldspar are often present, and large inclusions of metamorphic gemstone minerals like garnet, staurolite, and kyanite are common. The vast majority of the total volume of schist is platy minerals.The most common chemical sedimentary rock, by far, is limestone. Others include chert, banded iron formation, and a variety of rocks that form when bodies of water evaporate.
