So, is Q carbon a potential cutting tool, or just a phase in a process to make diamond dust? How does the crystal structure compare to diamond?

If you still have DeBoers stock in your portfolio after this, you are a loser.

I don't think it has crystal structure.It is amorphous like ordinary or metallic glass.

Ha.. now diamonds are a mans best friend.

And Q Diamond rings are due out .......when?

Can it be made as an aerogel?

Until they identify why they think it's a new phase, by identifying a unique crystalline structure, I will remain highly skeptical. It looks simply like yet another flavor of diamond-like carbon.
Glassy carbon is most definitely not a "new" phase.

Apparently Chuck Norris is considering it as a skin softener.

Finally, everlasting razor blades!
