The diamond for industrial use have become essential for producing cutting edge weaponry such as tanks.

Because of this, diamonds are no longer mere decorations, but have become an important industrial resources directly connect to a nation's power.

I have heard of what you're talking about.

But because diamonds are produced from nature, and the mining rights for it belong to British-based companies, they have the monopoly on most of it...

And since the relationship between Germany and the United Kingdom is deteriorating, if they cut off the supply of industrial diamond, our country will receive a big blow.

But if we can self-support ourselves with diamond within the country, we won't need to rely on other countries anymore...
