Diamonds are far from evenly distributed over the Earth. Clifford's rule states that they are almost always found in kimberlites on the oldest part of cratons, the stable cores of continents with typical ages of 2.5 billion years or more. Kimberlite pipes can be difficult to find. If they are visible in outcrops, the Diamonds are never visible because they are so rare. Finding kimberlites requires persistence, and only a small fraction contain Diamonds that are commercially viable. Since existing mines have lifetimes of as little as 25 years, there could be a shortage of new Diamonds in the future, making them a sensible investment.
