Diamonds are a very pure form of carbon, the building block of our world. Most commonly gem quality diamonds are clear, or "white", however sometimes impurities create coloured diamonds, far more rare than white. There is one mine however that produces a diamond that is coloured not by an impurity but huge forces deep underground. These are the fabled Argyle pink and red diamonds, the most concentrated form of wealth on the planet.
