The value is a 6% increase from the $541m sight in the same period last year and 3.7% higher than the $554m sight last month.
De Beers has increased efforts in recent months to find a way to verify the source of diamonds and ensure they are not from conflict area where rough diamonds may have been used to finance violence.
