Diamond, nature’s ultimate alchemy, is a crystalline form of pure carbon (C) forged under extreme pressure (45–60 kbar) and scorching temperatures (900–1,300°C) deep within Earth’s mantle, 140–190 kilometers below the surface. Over billions of years, volcanic eruptions carried these treasures upward in kimberlite pipes, where they await discovery as the hardest known natural material (Mohs 10).
