Even better:
golds scarcity and beatiful properties come from the fact that it cannot be created by humans. Heck, it cannot even be created by mother earth.
If there is a substancial amount of gold being created on your planet, it is most likely that your entire planet and solar system is being ripped apart. And left in total destruction.
This is because of the fact that it takes a star with 10 times the mass of our sun to explode in a supernova in order to create gold. Or colliding neutron stars. Those are some of the most powerful celestial events in the cosmos.
