Value of Botswana's Rough Diamond Exports Dropped in H1

Reuters reported that the value of rough diamond exports from mines in Botswana sank 15 percent during the first half of 2015. Diamond exports contribute a whopping 30 percent to the country’s GDP.

The bulk of Botswana’s diamond exports are from Debswana, a joint venture between the government and diamond giant De Beers. Debswana’s output slid 4% to 12-million carats in the first six months of this year.
Debswana, the world’s biggest diamond producer by sale value, has trimmed its full year production target to 20-million carats from 23-million carats.
