Diamond is recognized as the hardest natural material on Earth. This remarkable hardness is due to its unique crystal structure, in which carbon atoms are arranged in a tetrahedral lattice, providing immense strength. Diamonds are not only known for their beauty and brilliance in jewelry but also for their practical applications in cutting tools and industrial machinery. Their exceptional hardness allows diamonds to cut through other materials with ease, making them invaluable in various fields, including construction and manufacturing. Despite their durability, diamonds can still be chipped or broken under specific conditions, reminding us that no material is completely impervious.
