- Brown_diamonds abstract "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 and the United States, have resulted in brown diamonds becoming valued as gemstones in recent years. A significant portion of the output of Australian diamond mines is brown stones. A large amount of scientific research has gone into understanding 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 developed that heals lattice defects and converts brown diamonds into yellow or even colorless stones.".
