Coloured Gold

                                 
                                            
  • While pure gold is yellow in color, colored gold can be developed into various colors. These colors are generally obtained by alloying gold with other elements in various proportions.
  • To produce green gold, varying amounts of silver, copper, and cadmium may be alloyed in differing percentages to create a range of green gold shades. Gold in pinks to reds requires varying amounts of copper and silver. Some gold colors, such as purple and blue, contain aluminum and iron, respectively. These gold colors are much more difficult to produce but are stunning in appearance.
  • Certain colors may be limited to 10kt, 14kt, or 18kt. Generally white, rose, and yellow gold are available in all three karatages.
