Throwforward Thursday 61: The end of... diamonds

There are a lot of diamonds in the world - a total of about 6 billion carats (weighing around a million kilograms), with around 140 million carats mined every year. But known reserves will run out within a decade or so. That won't be the end of diamonds, though. We can now make diamonds in labs. Not "fake" diamonds - we can make real diamonds. But do we want to? Do you care, if you don't know the difference? Either way, we are facing the end of our current relationship with diamonds in the very near future. Diamonds - it seems - are NOT forever.
