Creation science and carbon dating
This is exceptionally striking evidence, because a diamond has remarkably strong lattice bonds (that’s why it’s the hardest substance known), so subsequent atmospheric or biological contamination should not find its way into the interior.
The diamonds’ carbon-dated ‘age’ of about 58,000 years is thus an upper limit for the age of the whole earth.
Some are found in these pipes, such as kimberlites, while other diamonds were liberated by water erosion and deposited elsewhere (called alluvial diamonds).
After two half lives, a quarter is left; after three half lives, only an eighth; after 10 half lives, less than a thousandth is left.
Diamond is the hardest substance known, so its interior should be very resistant to contamination.
But it is no problem or mystery at all if the uniformitarian/long-age assumptions are laid to one side and the real history of the world, given in Scripture, is taken seriously.
The C results are an independent but powerful confirmation of the stunning helium-diffusion results.
