Answer

Brief Explanations:

Natural diamonds form deep within the Earth's mantle, around 150 - 200 kilometers down, where high - pressure (about 50,000 atmospheres) and high - temperature (1000 - 1300°C) conditions exist. Carbon atoms bond together in a crystal lattice structure under these extreme conditions to form diamonds. They reach the Earth's surface through volcanic eruptions, specifically in kimberlite and lamproite pipes which act as conduits, transporting the diamonds from the mantle to the surface.

Answer:

Natural diamonds form deep in the Earth's mantle (150 - 200 km down) under high - pressure and high - temperature. Carbon atoms bond to form the diamond crystal structure. They reach the surface via volcanic eruptions in kimberlite and lamproite pipes.
