Africa has the largest producer in the world
Africa is not a country - it is a continent. Zimbabwe (a country within the continent of Africa) has largest known concentration of diamonds in the world.
Actually, I believe that Botswana is the largest producer of diamonds in the world. If Zimbabwe had as much in reserves of diamonds as Botswana, they would probably have their own currency.
Diamonds occur and have been collected from in these locations. Some are mined, others (alluvial) are found in river beds and at the mouths of rivers in salt water.

Most diamonds -- 75% of all diamonds mined -- are used by industry for enhancing cutting tools and precision instruments.
