Quite right Freya, industrial manufacture of diamonds for utensil purpouses is usually accomplished with high pressure combined with temperature, the micro wouldn't do that for you.
Glass cutters for instance cost a lot less than an engagement ring and the little wheel isn't transparent but it's the allotropic form of diamond rather than that of graphite or what.
Hyp: I find a way of cheaply making jewel quality diamonds, indistinguishable from the best of South African mines and I publish the recipe on the Net,
Th: The market value of diamonds will crash to dirt ground. There'd be no "big buck" for the internaut who takes the bother of trying it.
Unless, of course, you currently have investments in diamonds. In this case, try the experiment immediately, so as to know whether you should re-invest before it's too late!
