Talk:Isotopically pure diamond

14C
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 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? --Bob Enyart, Denver radio host at KGOV (talk) 18:31, 13 March 2012 (UTC)


 * Since the age of most diamonds is quite old (> 1 billion years) and given the relatively short half life of 14C (5,730 years), the amount of 14C in natural diamonds is effectively zero. 14C is produced by neutron capture by 14N (see natural production in the atmosphere). Neutron bombardment of diamonds would not increase the 14C contained in them because diamonds are composed of pure carbon and contain no nitrogen. Boghog (talk) 13:51, 13 July 2013 (UTC)

Ballistic conductor ?
List_of_thermal_conductivities says its a ballistic conductor (but the source isn't clear) - Do any of the source here confirm ? - Rod57 (talk) 20:01, 11 February 2018 (UTC)
