The world’s second largest 1,109 carat rough diamond discovered two years ago, has prompted the Botswana government to amend the law giving it first option to buy unusually large diamonds.
Botswana’s success has been due to the rough diamond mines.
An official told a local newspaper that it referred to stones that were unusually large, were particularly clear or had a rare colour.
The price will agreed between the government and the producer, both parties with the current market price of the rough stones.
