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)

Diamond Advertising Diamonds may be a girl's best friend, according to a concept popular in the 1950s. Alternatively, diamonds might also be forever, a concept popularized in advertising for several decades. Diamonds are a symbol of love, but they have hardly been the source of much loving interaction between various populations of humans.
