High Quality Content by WIKIPEDIA articles! Brown diamonds are the most common color variety of natural diamonds. The brown color makes them less attractive as gemstones and most are used for industrial purposes, however technical advances and improved marketing programs, especially in Australia, have resulted in brown diamonds becoming valued as gemstones in recent years. Australian diamonds, which constitute one third of the world production, are especially rich in brown stones. Large amount of scientific research was spent to understand the origin of the brown color. Several causes have been identified, including irradiation treatment, nickel impurities and lattice defects associated with plastic deformation, the latter are considered as the predominant cause, especially in pure diamonds. A high-pressure high-temperature treatment has been designed to heal lattice defects and convert brown diamonds into yellow or even colorless stones.
