Diamonds are formed deep within the Earth about miles or so below the surface in the upper mantle. Obviously in that part of the Earth it’s very hot. There’s a lot of pressure, the weight of the overlying rock bearing down, so that combination of high temperature and high pressure is what’s necessary to grow diamond crystals in the Earth. As far as we know, all diamonds that formed in the Earth formed under those kinds of conditions and, of course, that’s a part of the Earth we can’t directly sample. We don’t have any way of drilling to that depth or any other way of traveling down to the upper mantle of the Earth. The diamonds that we see at the surface are ones then that are brought to the surface by a very deep-seated volcanic eruption. It’s a very special kind of eruption, thought to be quite violent, that occurred a long time ago in the Earth’s history. We haven’t seen such eruptions in recent times. They were probably at a time when the earth was hotter, and that’s probably why those eruptions were more deeply rooted.

Therefore it should come as no surprise that creationists at the Institute for Creation Research ICR have been trying desperately to discredit this method for years. They have their work cut out for them, however, because radiocarbon C dating is one of the most reliable of all the radiometric dating methods.
This article will answer several of the most common creationist attacks on carbon dating, using the question-answer format that has proved so useful to lecturers and debaters. Answer: Cosmic rays in the upper atmosphere are constantly converting the isotope nitrogen N into carbon C or radiocarbon. Living organisms are constantly incorporating this C into their bodies along with other carbon isotopes. When the organisms die, they stop incorporating new C, and the old C starts to decay back into N by emitting beta particles.
