What landform are diamonds found?

Where are the diamonds found?
The mineral diamond is found on earth where volcanic pipes have blasted it to the surface from where it is formed, deep within the earth's mantel. Diamonds have been found in India, Africa -- several countries -- Brazil, Canada, Australia and even in the United States. Geologists find 'trace minerals', including kimberlite, that may indicate -- about one in 200 times -- that diamonds are included in the volcanic situation. When water flows over the top of a diamond-producing volcanic pipe and tumbles diamond stones along, diamonds can be found in riverbeds, or at the mouths of rivers as they empty into salt water. When a productive volcanic pipe is located, the land owner may choose to mine the area for diamonds.
