It's easy to deposit it as graphite which has lots of uses. So you'd
be dealing with large blocks of that.

Depositing it as graphene might be possible and that is *very* useful
stuff.

Heck, they could probably deposit it as diamond. Wouldn't affect the
gem market because it'd be easily detected as artificial. But diamond
has a lot of uses too. Especially as "slabs". It's one heck of a heat
conductor among other things. good for a lot of optical stuff too
(between the resistance to scratching and the high index of
refraction...)
