Radiocarbon in Diamonds Confirmed | Answers in Genesis

7/11/2007· In fact, if every atom making up the earth was carbon-14, even after just 1 million years there would be absolutely no atoms of carbon-14 left, because they would have all decayed away, based on today’s measured half-life! That’s why radiocarbon dating isn’t

How Diamonds are Formed: In Nature & In the Lab

The carbon material on its own cannot form a diamond. The conditions surrounding how diamonds are formed are precise and intense. A diamond needs both very high temperature and very strong pressure in order to metamorphose from its basic carbon form into the gem we see in jewelry all over the world.
