The diamond mining game has maybe 5 years left, large mined and coloured stones will always be valuable, but not valuable enough to run large mining operations subsidized by smaller stones.


The history of mining kimberlite pipes clearly indicates that it is pipes that contain very large diamonds that have been reliably profitable, regardless of average grade. For example, the Premier pipe average grade is reported at about 40 cpht, however, annual profits were made by just a few very large stones every year which represented a small fraction of 1% of total diamond carats recovered. The secret is to identify those pipes that have potential to host very large diamond regardless of average grade, and that clearly explains why Rio Tinto is spending $60 million to evaluate Fort a la Corne pipes.
