Beautiful, unique, historical, and captivating. Value: $450.3M. I think the held orb and reference to the mysteries of the Universe (or heavens) is what makes it original. Think it's worth such money? Lots of great humanitarian things could be done with that kind of money but there's something to be said for art.
No, of course, it's not worth that much money except in the capitalists' hall of cards. Was it purely an extravagant purchase by a Saudi prince? Don't know. Do know it's headed for the Louvre Abu Dhabi. If they're true capitalist then they'll display it and it'll bring in billions. So, it depends on how they use it whether it was worth the $450 mil (in this capitalist world that doesn't respect anything but money).
