Definition
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay
Kimberlite is a rare, blue-tinged, coarse-grained intrusive igneous rock, which sometimes contains diamonds and is mostly found in South Africa and Siberia.

Formation
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
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.

More about Claystone and Kimberlite
Here you can know more about Claystone and Kimberlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Claystone and Kimberlite consists of mineral content and compound content. The mineral content of Claystone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Kimberlite includes Garnet, Olivine, Phlogopite, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Claystone vs Kimberlite, the texture, color and appearance plays an important role in determining the type of rock. Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Kimberlite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Claystone is Rough and Dull and that of Kimberlite is Dull and Banded. Properties of rock is another aspect for Claystone vs Kimberlite. The hardness of Claystone is 3.5-4 and that of Kimberlite is 6-7. The types of Claystone are Not Available whereas types of Kimberlite are Basaltic Kimberlites and Micaceous Kimberlites. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Claystone and Kimberlite is white. The specific heat capacity of Claystone is 0.92 kJ/Kg K and that of Kimberlite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Claystone is heat resistant, impact resistant whereas Kimberlite is heat resistant, impact resistant.
