In Pokémon Diamond, you can obtain Rock Polish by leveling up your Pokémon that can learn the move, or by using a TM (Technical Machine) if it's available. The move is typically learned by Rock-type Pokémon as they gain experience. Additionally, some Pokémon can be taught Rock Polish through breeding. To find the TM for Rock Polish, explore areas where TMs can be found or purchased in the game.

Kimberlites are the rock type that diamonds are usually found in. They are formed when a magma from deep in the mantle drills its way to the surface in a fast gaseous explosive event. Diamonds typically occur as xenocrysts within the Kimberlite matrix. the volcanic deposits are called Lamproite igneous volcanic pipes. Please see the related links.
sedimentary
Diamond is a form of carbon mineral that is classified as a type of metamorphic rock called Kimberlite. Diamond crystals are often found embedded within Kimberlite rock formations deep within the Earth's crust.
Daimond is not a metamorphic rock because it is a mineral.
No, schist is a metamorphic rock type.
