Diamonds are mined in about 25 countries. India was the initial source, followed
by Brazil and then South Africa. Africa is the richest continent for diamond
mining, accounting for roughly 49% of world production. The major sources are in
the south with lesser concentrations in the west-central part of the continent. The
major producing countries are Congo Republic (Zaire), Botswana, South Africa,
Angola, Namibia, Ghana, Central African Republic, Guinea, Mali, Sierra Leone,
Tanzania and Zimbabwe. Canada is starting to come on line now with Ekati and
Diavik.in the northern part of the country. Australia has one producing mine, the
Argyle. There are major resources in Russia. The United States has very minor
deposits in Colorado, Wyoming and Arkansas.
