D
Most of the world's diamonds come from Africa,but there is one place in the United states where they are found,it is near Murfreeboro,Arkansas.
Diamonds were first found near Murfreeboro in 1906.About fifty thousand diamonds have come from this field.One forty-carat diamond was the largest ever found in North America.But most of the stones were too small to be worth mining.Soon all mining stopped there .Today a visitor to Murfreeboro can hunt for diamonds himself.
A few diamonds have been found in sand and gravel along the Great Lakes,too.But none of these were in their original blue ground.They may have been formed far in the north and carried south by the last great glaciers.
