No one owned that gem when it was just sitting in the ground. It took millions of years to create.
Some capitalism claimed it when one of his workers mined it. Calculated how much energy and labor it has costs to obtain it.
Then sold it for a massive markup compared to their own costs.
The machines have spend energy to get it (loss)
The workers spend life time and life energy to get it (loss)
Bezos his works spend their life time and energy to make him the money he now loses on this ring. (Loss)
The planet lost one of its rare gems. (Loss)
No lives are going to be saved using that rock, its not going to be used for breakthrough science, its not in a museum where we the people can admire our planet and learn from the its amazing processes. (No profit)
Instead its to decorate a hand so one person can be perceived as having value. Ironic.
