are brought from the mantle to the surface in magma that hardens into kimberlite.

Explanation:

Diamonds were formed billions of years ago due to the heat within the Earth's crust. The pressure and heat then results into diamonds which are formed from the crystalization of carbon atoms.

Therefore, diamonds are brought from the mantle to the surface in magma that hardens into kimberlite.
