WebThe mantle makes up 83% of the Earth's volume. It's composed of molten rock called magma. In the rare occasions where it reaches the surface, we call it lava. The mantle is hottest near the center of the Earth, and heat currents keep it in constant motion. The crust and mantle meet in a tumultuous zone with high pressures and temperatures. WebLab-grown diamonds are made by replicating the natural process of diamond formation. The most common method is called chemical vapor deposition (CVD) and it involves using a combination of gases, heat, and pressure to create an environment that encourages carbon atoms to form together into a crystalline structure.
