One of these locations is the Lamproite Belt in Australia, where diamonds have been found in lamproite stones. Lamproite is thought to form when mantle-derived magmas interact with metasedimentary rocks in the upper crust.A diamond, made of pure carbon, is both a jewelry gemstone and a durable material in industry. There are two types of diamonds: gem diamonds and industrial diamonds. The diamond is found in igneous rocks called kimberlite. It is a mineral c...If you’re a diamond lover, you know that finding the perfect diamond can be an exhilarating and daunting task.

They are mantle rocks that contain less than 45% silica (peridotite or eclogite). Thick continental crust is required to melt the mantle rocks that are the magma source.

Typically, the kimberlite pipes that contribute to the creation of diamonds are the ones located in ancient cratons.But it still is a great question. Well, the answer is yes! But it can’t be any type of lava – which means that it can’t be any type of rock, either. To be precise, there is only one rock that we managed to find that can both contain diamonds and melt into lava and end up on the surface. That rock is called a kimberlite.Deep diamonds from Collier-4 from the Juina area, Brazil.
