It is possible to determine where a diamond originated from whilst it is in the rough form. As soon as the diamond is cut, however, it is virtually impossible to distinguish its origin.
The map below shows the location of diamond mines throughout the world. Scroll over each country to see a brief description.
Until the 18th century, India was the only supplier of diamonds in the world. Diamonds were discovered in Africa in the early 19th century and subsequently became the largest producer worldwide, relying on Zaire for industrial diamonds and South Africa for gem quality diamonds. Since the early 80's, Australia has been producing the most diamonds worldwide.
