This is a question without an answer.
What is clear, however, is that extracting diamonds from the earth is expensive and dangerous: diamonds are not as common as air or water, for example.
It is not possible to determine how many diamonds there may be on earth, but it may be accurate to write that diamonds are not necessarily 'in abundance' on earth.
Diamonds are mined, so whatever effect mining may have on the earth is made when diamonds are mined.
Since the natural resource of diamonds has not been exhausted, it is not possible to estimate how many diamonds are on --and in -- the earth.
All diamonds are erupted to the surface of the earth by volcanic pipes. Exceptions are diamonds that arrive on earth from unknown sources in space. Diamonds are found on every continent on earth except Europe and Antarctica.
Diamonds are found on every continent on earth except Europe and Antarctica.
Most diamonds are found on the earth and in the earth near indicator minerals, such as kimberlite.
No, diamonds don't surround the earth's mantle. Diamonds are formed within the earth's mantle, and are rare.
The abundance of radium in the earth crust is 9.10-10 mg/kg.
Diamonds are formed deep within the earth's mantle.
The earth is mined to get diamonds.

Protactinium is so scarce that the abundance in the Earth crust was not determined.
One thing would be it's natural abundance of diamonds.
Diamonds have to be mined by humans
Diamonds are the hardest mineral on earth.
Natural diamonds that erupt to the earth's surface were formed with the earth. Diamonds that come to earth from space may have been formed before earth: that research hasn't been documented to date.
