The value of the diamond production in 2000 in the three main countries beginning where conflict diamonds primarily originate has been predictable as follows Angola, $739.7 million. D.R.Congo, $585 million ,and sierra leone, $87.5 million of that manufacture only a fraction is comprised of conflict diamonds but that production is not definitely known. Estimates of annual diamond production and trade value in countries where conflict diamonds are mined vary widely since they rely on disparate mathodologies and because detailed data are often lacking.
