When I worked semi-flash man , I learned in trading seminar. How do you know how to mine diamond???
Now-days Diamond is mining by works . So you should know about it to get so many war history in Africa.
In my opinion There are also aspects that diamonds don’t think so beautiful
That is why Sumitomo Zaibatsu is the worst company in the world. They control mind first. Their Trading tells me that it will be a war and makes me not do bad things. With inside and outside the company enemies.
