Why can diamonds form in the mantle

Definition1/13
The weight of the rocks above the mantle results in high pressure. Diamonds need high temperatures and pressure to form from carbon. Diamonds form in the mantle in certain zones where conditions are right for them to do so.
There just happens to be the right critical temperature-pressure-mineral environment in the mantle in certain zones for their formation.
