Diamonds are mined from Kimberlite through three types of diamond mining alluvial mining pipe mining and marine mining. How are diamonds mined Meet the 3 different methods. Alluvial diamond mining occurs in riverbeds and beaches where thousands of years of erosion and natural forces such as wind rain and water currents wash diamonds from their primary deposits in kimberlite
