The toughest natural material on Earth is diamond, which is formed under extreme pressure and temperature deep within the Earth's mantle. Its unique atomic structure, where carbon atoms are arranged in a strong tetrahedral lattice, gives diamonds their exceptional hardness. This property makes diamonds resistant to scratching and abrasion, allowing them to be used in various industrial applications, as well as in jewelry. Their hardness, however, can also lead to brittleness, making them susceptible to breaking under certain conditions.
