which makes me wonder if microwave-heated water is really different than convection-heated water, inasmuch as Human consumption is concerned.
*sigh* You're useless. Water forms many SOLID molecular structures. You can't form molecular structures in a liquid. Also, MICROWAVE PARANOIA, tinfoil hat time. Aside from boiling your food, microwaving it is by far the safest way to cook food because you don't get any carcinogens from grilling or frying it.

That doesn't seem to happen with diamonds that are worked (as industrial diamonds in drill bits, etc.) such that they would reveal such a process.
Actually they do. That's why they still sell diamond needles for old record players; the needles get worn out through heavy use and have to be replaced.
Your original assessment is flawed anyway; much more than the top layer of diamond is lost in a drill pass. Fun math time, diamond has a density of 3.5 g/cm^3, carbon 12 g/mol => there are 1.76e+23 carbon atoms per cubic centimeter of diamond. If only the top layer of carbon were transformed to graphite and seared off in each drill pass, it would still take more than the age of the universe to run through a drill bit.
