This flipping Koh-i-Noor thing. I'm currently sitting looking at a prettier light bulb (and the bulb is a lot more useful)
It has zero value, except what we choose to ascribe to it.
The world would be a better place if we stopped ascribing any value to diamonds at all. A burnt chunk of charcoal is mostly exactly the same type of atoms.
Why are we keeping this clutched in our sweaty little mitts, when it matter to other people, and who ever is the rightful owner, it certainly isnt us.
Give it back to whoever would have it now if instruments of the British empire hadnt robbed them.
And if they didnt have it legally, then its up to them to pass it back or sit and gloat, and look silly, which we currently do
For goodness sake!
