In the cases of the kimberlite or lamproite pipes, open-pit mining is most commonly used. This involves a progressive digging at the source of the pipe (Open Pit, No Date). In effect, a giant crater is created that allows for transportation of trucks, people and heavy equipment to the bottom (Open Pit, No Date). A mining operation will dig deeper and deeper into the pit, excavating diamonds and their rock hosts. Sometimes, diamonds and their kimberlite or lamproite hosts have been deposited above and around the pit (known as eluvial deposits), which are much simpler to mine (Learning About, No Date).

Of course, once diamonds are extracted from rocks, a skilled process of sorting ensues. Diamonds are manually sorted by experts who determine issues such as size, quality and color to assess whether the diamonds will be sold as gems or to industrial clients. The diamonds are often routed through the Diamond Trading Company - formerly the Central Selling Organization - which has an almost cartel-like influence on diamond distribution (Diamond Trading Company, No Date)

In fact, diamonds have been at the root of intense and deadly strife in Sierra Leone, most notably,
Diamond-Water Paradox The diamond water paradox is a classic example of the numerous paradoxes that can be seen in everyday life. According to the diamond water paradox, the cost of diamonds is more than the cost of water despite the fact that water is essential for human existence while diamond is more of an optional luxury item. A good application of this paradox is the difference in the wages of essential
"In the case of arms trafficking," they advise, "there are arms dealers eager to sell AK-47s to conflict zones all over the world. There are shipping and air transport services willing and able to transport the weapons to warlords who are destabilizing much of West Africa.

On page 114 Campbell explains that at about the same time -- ironically -- that he was being pitched by the De Beers people about the "huge economic impact that bad publicity about conflict diamonds could have on sales" planes piloted by Al Queda were crashing into the World Trade Center.
