What is diamonds parent rock?

Diamonds are formed from carbon and are typically created under high-pressure and high-temperature conditions deep within the Earth's mantle. The parent rock of diamonds is usually kimberlite, a type of igneous rock that can transport diamonds from the mantle to the surface during volcanic eruptions. Another less common parent rock is lamproite. Both rock types are associated with the geological processes that allow diamonds to form and be brought closer to the Earth's surface.
