ELI5 What the Russian diamond announcement means to the diamond market, the global market as a whole, Russia, and DeBeers.

This seems like a huge announcement. What does this mean?

1. Some smart people found some really hard rocks in the ground 40 years ago.
2. Things in the ground are hard to get out of the ground. Especially when they are really hard rocks.
3. Some other people decided not to tell anybody about the rocks in the ground because they were busy "playing" with their "friends" and had already decided to make their own really hard rocks.
4. They finally told everyone about their cool rocks.

5. The rocks are still going to be really hard to get out of the ground and it will take a lot of time.
6. The rocks aren't very pretty so they'll mostly be used for really big machines that need really hard rocks.
7. There are A LOT of these rocks. More than anybody has ever found before.
8. **This means** that once they get them out of the ground, lots of people will be able to use them in lots of different big machines (especially big machines that get very hot or that cut very hard things) and that those machines will create useful things for everyone. 
9. But again they still have to get them out of the ground.

Some other people (like DeBeers) mostly deal with the really pretty and shiny rocks. They already have plenty of those anyway so even if there are more nice rocks in Russia, they probably won't want any more. They certainly won't want to sell their rocks for less money.
