Curtin University researchers discover Earth has been making diamonds from waste – ABC News

Dr Doucet said the researchers discovered “deep diamonds” formed in the Earth were predominantly made up of organic matter from dead plants and animals.  “This research discovered the Earth’s engine actually turns organic carbon into diamonds many hundreds of kilometres below the surface,” he said. “While recycling is becoming a modern-day necessity for our sustainable survival, we were particularly surprised to learn, through this research, that Mother Nature has been showing us how to recycle with style for billions of years.”
