Natural Colored Diamonds are found throughout the world. They occur approximately once in every 10,000 diamonds. As with white diamonds, the majority of the highest yield mines are located on the continent of Africa. However, there are high production mines in South America, Australia, Russia, China, and North America. In fact, the Argyle Diamond Mine in Australia is one of the most famous and has contributed greatly to the popularity of fancy pink diamonds. Other areas such as Angola, the Ivory Coast, and Brazil are also known for their diamond mines.
