RE:RE:RE:Big change announced Could not agree more, the diamond mines are so good that it makes sense to purely focus on them. Just look at Oena, the price per carat was $1400 or 14 higher than the global average. And the diamonds at the Angola mine might be also of above average quality, some other nearby mines manage to produce diamonds sold at $500/carat which is still 5 times the global average.
In comparison, De Beers avg price per carat is "only" at $171.
