The diamonds collected in the recovery process are cleaned in an acid solution, washed, weighed and packaged in sealed containers for transport. In accordance with the Kimberley process, these containers are sealed with a tamper resistant seal, numbered on site, and a certificate of origin is issued.
When it comes to finding or mining diamonds, there is very little good information available. Geologists who search the world over for new diamond bearing kimberlite deposits are .
We have already described how diamonds are brought to the surface of the Earth in kimberlite and lamproite pipes, and that these volcanic events occur within continental cratons, where the conditions exist to help diamonds maintain stability on their journey to the surface.
Kimberlite is basically a form of peridotite in other words composed dominantly of olivine, a particular type of chrome rich granite and you'll see why this is important when we come to talk about diamond .
"The pipes appear to have formed by a twostage process: (1) pipe excavation, where a large hole is blown out of the ground, and (2) pipe infilling, where kimberlite lava and ash fill up the hole. The pipe was infilled my multiple phases of eruption and each of these phases carried different diamond contents.
Diamond is relatively easy to recognize, but there are very few prospectors, geologists or jewelers with experience in recognizing uncut (rough) diamonds. One of the easiest methods is to use a relatively inexpensive device marketed as a 'Diamond Detector ' or 'Diamond Detective'.

Livingstone Marufu Business Reporter THE Zimbabwe Consolidated Diamond Company (ZCDC) has invested 30 million in kimberlite mining and plant equipment from South Africa in a bid to exploit minerals for sustainability and growth.. Of the total amount, 15 million is for mining equipment from South Africa and another 15 million is for setting up of the plant locally.
Diamond prospectors know that the secret to finding diamonds is to locate rocks called kimberlites. A new study in Nature this week may help them focus their search a bit more closely, and also ...
Establishing diamond grade is a laborious process that combines bulk assay for diamonds in large amounts of exposed kimberlite (in some cases hundreds of tons) with core drilling of the unexposed kimberlite. The goal of this process is to accurately estimate the size of the kimberlite that could be mined (figure 14), the carats of diamond per ...
Seismics are particularly useful in finding kimberlite dykes in Canada's north, which tend to be gently dipping, because the sound waves can more easily delineate bodies that have shallow orientations.
