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.
