Diamonds and Strata Have Too Much Carbon-14

Natural diamonds are believed to have been formed deep underground in the upper mantle of the earth’s crust. Under extreme temperature and pressure, pure carbon is formed into the diamond’s crystalline form. Over time, the diamond is moved upwards by rising magma. Natural diamonds are commonly believed to have been formed millions of years ago.

If the rate carbon-14 decays has been consistent, any carbon-14 older than 100,000 years is undetectable by current measuring techniques.

But carbon-14 has been measured within natural diamonds. Either the decay rate of carbon-14 is not uniform, the diamonds are younger than believed, or both. Carbon-14 in diamonds is evidence that the earth is thousands of years old, not millions.
