Rough diamonds can be sorted into 3 distinct categories: Gem quality: only about 20% of all rough diamonds are good enough for jewelry. Industrial quality: 80%, while of good quality, are reserved for industrial use. Crushing-boart or boart: stones with the worst diamond quality are crushed to be used as diamond dust (used to cut and polish gem

Crushing . Since kimberlite is formed underground, it is a relatively hard rock, similar to granite. The first step to finding the ‘needle in a haystack’ diamond, is crushing the kimberlite ore. This has to be done in a controlled way in order to avoid breaking or damaging the diamonds trapped inside.

When the diamond-rich depth is reached, the raw material extracted from the ground is then transported to a special screening plant for further processing. There’s another form of alluvial mining called artisanal mining. In essence, it is basically the same method employed by gold diggers which involves the screening and straining of mud.

This process reduces large run-of-mine lumps into smaller pieces, making them easier to handle, and releases or liberates the diamonds to be recovered in subsequent steps.
