Diamonds are an impressive material, possessing amazing qualities. As most of us are aware, diamonds are unique in that they are formed of the single element carbon, which is the same as a pencil lead or charcoal. Of course, being transparent in its purist form and the hardest mineral, they are vastly different from either of these two relatives.
Diamonds reach the surface in volcanic pipes after being formed deep in the earth. But these aren’t your ordinary “pipes,” only certain volcanoes contain diamonds. These volcanic anomalies are called kimberlite pipes, named for the town of Kimberly, where the South African diamond rush was started in the 1869. Areas where these pipes are common lead us to the diamond producing regions of the world.
Where in the world?
Currently, most diamonds that are sold come from either Africa, Russia, Australia or Canada but you may be surprised to find that there are plenty of places across the globe where diamonds are naturally found in abundance.
• India was the original diamond source for hundreds of years, up until the late 19th century. Many famous diamonds originate from the Golconda region. The term Golconda is now synonymous with the chemically pure, colorless diamond that is most desired by astute diamond aficionados.
• South Africa established itself as the new diamond source in the late 1800's, producing ample, consistent quantities of diamond rough replacing the now depleted Indian sources. Other African countries have since become major contributors to the diamond supply line.
• Russia has more recently become a significant diamond source, known for its high quality rough.
• Canada is another contemporary source, which yields much less than either the South African and Russian pipes.
• Australia is unique that is produces a significant volume out of one single mine in a remote region, called the Argyle mine. The Argyle is the primary supplier of pinks, purple and the extremely rare red diamond.
• The United States has some Kimberlite regions, but only one yields any diamonds and is solely a tourist attraction. This pipe is located in Arkansas and called Crater of Diamonds State Park. Occasionally, we hear news of a lucky tourist happening upon a larger diamond rough, which they get to keep!
