assume that the manner in which the 14C ends up as a component is irrelevant to its factual existence as an isotope in diamonds. So I'm wondering if that isotope should be recognized and listed. Otherwise it seems readers will end up with a false impression about the actual composition of natural diamonds. Any thoughts? --

Shouldn't 14C be added to this: "Compared to natural diamonds that are composed of a mixture of 12C and 13C isotopes..." so that it would read: "Compared to natural diamonds that are composed of a mixture of 12C, 13C, and 14C isotopes..." Natural diamonds have carbon-14, perhaps by neutron capture. I
