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.
Sandstone is defined as a rock which is composed of sand-sized grains of various minerals mostly of uniform size and often are smooth and rounded

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.
Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.

All about Kimberlite and Sandstone Properties
Know all about Kimberlite and Sandstone properties here. All properties of rocks are important as they define the type of rock and its application. Kimberlite belongs to Igneous Rocks while Sandstone belongs to Sedimentary Rocks.Texture of Kimberlite is Porphyritic whereas that of Sandstone is Clastic, Granular, Rough. Kimberlite appears Dull and Banded and Sandstone appears Rough. The luster of Kimberlite is subvitreous to dull while that of Sandstone is dull. Kimberlite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Sandstone is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. The commercial uses of Kimberlite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo) and that of Sandstone are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones, used in aquariums.
