Diamond loaded rock was came from lost planet

A research has shown that in 2008 which Diamond loaded rock was buried in earth space was related to a planet in the early period of the solar system.
This planet was part of the system solar billions of years ago and destroyed by another planet and was destroyed. Its volume was as much as Amrit or Mars.
Scientists say that only diamonds can be formed in such a large planet.
Scientists reviewed the diamonds linked to the latest microscope. The pieces of this rock were fallen in Nobah's desert in northern Sudan.
Scientists say that this is the first fatal witness to disappearing of a large planet.
This discovery strengthens the theory that the solar system initially had a sediment of planets, and the present planets have been associated with the remains of their planets.
