Occasionally a diamond mine is productive enough to continue as an underground mine after it turns into too deep to be successfully pit mined.
Open pit diamond pipe mining is the most common method to recover diamonds immediately from kimberlite pipes.
Blasting loosens the diamond bearing rock and huge earth-moving machines load the ore into large 300-tonne vehicles that take it to a diamond processing plant.
The diamond world has turn out to be much more clear too.
USES Diamond is crucial gemstone in the jewelry business.

Another crystal behavior is ball-shaped agglomerates of radiating crystals.
