Diamond is the hardest substance known, so its interior should be very resistant to contamination.
Diamond requires very high pressure to form—pressure found naturally on earth only deep below the surface.
) is only 5,730 years—that is, every 5,730 years, half of it decays away.
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.
Some are found in these pipes, such as kimberlites, while other diamonds were liberated by water erosion and deposited elsewhere (called alluvial diamonds).
According to evolutionists, the diamonds formed about 1–3 billion years ago.
In AMS dating, researchers use an accelerator-based mass spectrometer to count all the C14 atoms, rather than just those atoms which are decaying. Since carbon is fundamental to life, occurring along with hydrogen in all organic compounds, the detection of such an isotope might form the basis for a method to establish the age of ancient materials. Libby, a Professor of Chemistry at the University of Chicago, predicted that a radioactive isotope of carbon, known as carbon-14, would be found to occur in nature.Definition: AMS (Accelerator Mass Spectrometry) radiocarbon dating is a way to obtain radiocarbon dates from samples that are far tinier than that needed for standard radiocarbon dating.Standard c14 dates require amounts of between 1 and 10 grams of charcoal; AMS can use as little as 1-2 milligrams, and under special circumstances to samples as small as 50-100 micrograms.
