You may wish to look at my old note here to understand why did I delete it. I have analyzed that article, and being a professional in the diamond spectroscopy, found the evidence unreliable, with no slight to you or the authors. Materialscientist (talk) 23:34, 4 August 2009 (UTC)
 * I was disappointed to read your comment at Talk:Synthetic_diamond. Which covered behind the journal names instead of replying as a scientist. The JACS paper does appear as a mistake - the "diamond" Raman peak is much too sharp for the given grain size and character of the synthesis. Its shift with excitation wavelength (Fig. 8) is incompatible with the Raman nature of the signal. I can't access, but by the same authors is much more convincing (look at their Raman!). Still, that paper contains serious problems with XRD assignment (too many background signals and speculative diamond phases involved), and the Raman peak at 650 cm-1 may not be due to diamond (again, strong, too sharp and wrong position for nanodiamond). This evidence is enough for me to suggest that diamond was possibly produced, but you need to work much harder to prove that to the community. Claims of revolutionary new diamond synthesis were many and most were rejected later. In such unclear situations (including personal interest by yourself), WP requires acceptance of the results by the scientific community (this is called "secondary sources"). Regards.
