Definition
Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities
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
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
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.
