Indulge in the following fantasy. You wake up one morning, turn on your water faucet and out comes a stream of perfectly shaped nuggets that look like diamonds.
On further investigation find that all your water taps are spewing out what seems to be diamonds. You rush to your neighbor, who happens to be a jeweler. He assures you that the diamonds are indeed genuine but reports they are coming out everyone’s taps worldwide.
Diamonds suddenly have become as plentiful as water and water has become as difficult to obtain as diamonds.
