Riddle of the day: Die-monds and Diamonds

?

PLEASE KINDLY RETURN ALL STOLEN TREASURES AND KNOWLEDGE TO THEIR RESPECTIVE OWNERS
AS ANCIENT SAYINGS GO
TO TAKE WITHOUT PERMISSION IS THEFT
WHICH IS PUNISHABLE UNDER THE DIVINE LAW
START BY DIGGING (MENTALLY) YOUR OWN MISGUIDED HISTORY AND LEARN ABOUT HUMILITY

?
How much does it cost (souls, deaths, horror, suffering, pain, slavery, lost of loved ones, loneliness, hatred, money, lastly Hope) to mine Die-monds,
Which are just plain carbon, the very composition of your own flesh?
