Diamonds come into being under temperatures and pressures that only exist around 100 miles (~160km) beneath the surface. It is a long journey until they reach the surface close enough so that they can be excavated by humans.

Given its journey from such a depth, finding a stone of perfect clarity is a great feat, since its carbon structure was not contaminated during its rise to the sunlight. Making it not only 58 times harder than any other material in nature, but providing it with light reflecting properties that are hard to match.
