Somewhat, yes. It seems that graphite is a somewhat more relaxed state than carbon's diamond crystal allotrope. Both burn, and can be vaporized with LOX/acetyl

Somewhat, yes. It seems that graphite is a somewhat more relaxed state than carbon's diamond crystal allotrope. Both burn, and can be vaporized with LOX/acetyline torches: http://www.popsci.com/sites/popsci.com/files/styles/medium_1x_/public/import/2013/images/2009/08/diamond3.jpg http://www.popsci.com/sites/popsci.com/files/styles/medium_1... But apparently, over long periods of time, and unless coerced, carbon prefers to be graphite and so, diamonds can decay as such.

Hence why graphite is generally more plentiful than diamonds.
