What's On The Edge Of A Diamond?

I realise it's a crystal lattice, but the diagrams merely show the edges going on forever, how diamonds have fixed shapes, what happens at edges? Surely there aren't just carbon bonds floating around.

I googled quickly and arrived resultantly at the wiki for it:

Right off the bat, I have to ask what contamination is introduced into the water by "subjecting [it] to high energy sound waves".  As you know, water bubbles that energetically form bubbles and then collapse is very abrasive, so all this sonic action in any container would likely abrade the contain and this contaminate the water.

Thanks for the info on Penta Water.  I had great fun reading the wiki.  Apparently, from making too many fraudulent statements about their snake oil, the Penta folks are currently off the net.

You know, there is a way of doing some informal but fairly reliable testing of "types" of water, based upon preparation.  Pot 3 sets of 3 plants each from the same seedstock or cuttings.  Place them in the same environment, and water them precisely with the following:

1. cooled-down water that was boiled on the conventional stove
2. cooled-down water that was boiled in the microwave
3. tap water

Use 3 plants in each set to obtain average behavior.  Make sure the pots are absolutely clean to begin with, and of course use the same batch of well-mixed soil from a reliable source.
