Not sure if there is a way to invest, but Russia has a little secret...

That might just make them relevant again.

The trillions of carats of diamonds (that's hundreds of thousands of tons) that are located underneath the Popigai crater in Siberia represent 10 times as much raw diamond as the entire world's supply of the diamond reserves all put together. Apparently, the Russians have known about the diamonds for about 40 years, but they've been happy to just keep it a secret and go on selling us all diamonds from other places in Russia instead.

Just to be clear these are impact diamonds, or industrial diamonds, not gems stones for jewelery, but still... That's a lot.
