There is the following simple logic: under controlled conditions one can ensure that the perfectly periodic tetrahedral structure is realised, whereas natural diamonds have inclusions in them and flaws. It may well be that some natural diamonds could be harder owing to certain kinds of covalent bonds being formed with substances other than carbon, but it would have to be a fairly "systematic" "brewing" of the right mixtures, so one would have to account for what gives rise to these conditions.See also physics.stackexchange.com/a/88306/26076 | |
