The reason why Bluerock is in the top 10 producers is not because of volume but of quality of diamonds. Hence, we see a much higher value per ct associated with our stones. This value per ct puts Bluerock in the top 10 in the world.
Let’s face it the only reason we are mining here is that reason. The high volume mine may produce a lot of stones but most are destined for the crusher and industrial paste. Only around 10% are of Gem quality. With Bluerock this rises to around 75% by volume and 95% by value.
A little bit of background to this may be found here.
Once rough diamonds are mined, they are sorted into three categories: gem quality diamonds, industrial diamonds, and crushing bort (industrial diamonds of inferior quality that, once crushed, become diamond powder). Most diamonds are destined for industry. Only the highest quality diamonds in terms of color and clarity, of little to no fluorescence, and with few flaws can be used in jewelry, and of the gem quality stones, only the best ones become investment diamonds.
Diamonds are first sorted right after mining and then placed into the CSO (Central Selling Organization). The stones are sorted according to their weight in carats, their color, clarity, and shape (of the rough diamond). Finding rough stones of high quality is extremely difficult. When a diamond is mined, over 250 tons of earth must be moved to find a diamond of gem quality. BLUEROCK every 30 tons). Ten times that must be extracted to find one carat of investment quality rough diamond. It goes without saying then that investment diamonds are incredibly rare. This rarity is what sets them apart from other types of diamonds.
So Bluerock is a top diamond producer in terms of quality and value per ct mined. This also means that for a rough stone, the most important criterion is the shape of the diamond. The best shapes are octahedron and dodecahedron because they offer the most profit.
The price rises exponentially with the size of a diamond. A 1.1 carat stone will be worth much more than a stone slightly less than 1 carat for example.
If you look at Bluerock stones, you will see they fit this criterion of shape and that is why the latest 10ct+ diamond will fetch more than $5000 per ct.
