Definition
Kimberlite is a rare, blue-tinged, coarse-grained intrusive igneous rock, which sometimes contains diamonds and is mostly found in South Africa and Siberia.
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

Formation
Kimberlite is an igneous rock and is the main source of diamonds. Its formation takes place deep beneath the Earth’s surface between 150 to 450 kilometres, and are erupted rapidly and violently.
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

Kimberlite vs Limestone Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Kimberlite vs Limestone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Kimberlite and Properties of Limestone. Learn more about Kimberlite vs Limestone in the next section. The interior uses of Kimberlite include Countertops, Decorative aggregates, Homes and Interior decoration whereas the interior uses of Limestone include Decorative aggregates and Interior decoration. Due to some exceptional properties of Kimberlite and Limestone, they have various applications in construction industry. The uses of Kimberlite in construction industry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Limestone include Cement manufacture, Cobblestones, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar, Roadstone, Source of calcium.
More about Kimberlite and Limestone
Here you can know more about Kimberlite and Limestone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Kimberlite and Limestone consists of mineral content and compound content. The mineral content of Kimberlite includes Garnet, Olivine, Phlogopite, Pyroxene and mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Igneous Rocks. When we have to compare Kimberlite vs Limestone, the texture, color and appearance plays an important role in determining the type of rock. Kimberlite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas, Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors. Appearance of Kimberlite is Dull and Banded and that of Limestone is Rough and Banded. Properties of rock is another aspect for Kimberlite vs Limestone. The hardness of Kimberlite is 6-7 and that of Limestone is 3-4. The types of Kimberlite are Basaltic Kimberlites and Micaceous Kimberlites whereas types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Kimberlite and Limestone is white. The specific heat capacity of Kimberlite is 0.92 kJ/Kg K and that of Limestone is 0.91 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Kimberlite is heat resistant, impact resistant whereas Limestone is pressure resistant.
