Why is Africa full of diamonds?

Africa’s diamond wealth comes from ancient geological processes that formed diamonds 600 million to 3 billion years ago, pushed closer to the surface by volcanic activity.

Diamonds didn’t just pop up—they formed deep in Earth’s mantle under insane heat and pressure. Millions of years ago, volcanic eruptions shoved them closer to the surface. Africa’s stable cratons? Perfect for forming and preserving diamonds.

Why is Africa so poor if they have diamonds?

Africa’s poverty hangs on despite diamond wealth because of illegal trade, underreporting, corruption, and tax evasion.
