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.
  
Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel

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.
  
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
