The world is 4.5 billion years old, and the oldest diamonds are about 3.3 billion years old. That’s really old.
To put that into perspective for you: the human being has only been existent for around 200,000 years.
However, it has been calculated that even if this change were to take place it would take over ten billion years to happen.
Now back to the diamond’s age. Scientists reason diamonds may have been starting throughout earth’s history.
Many have been discovered that are three-point-three billion years old. And the new ones are a mere one billion years old.
