Minor creation ---> Diamonds?

[Staatskommissar]

While diamonds aren't made from coal, but rather carbon deposits, you could make a diamond from coal, albeit with many impurities.

And since since coal is essential a form of vegetable matter could wizards not create (flawed) diamonds or better yet create things MADE OUT of diamonds?

chains
long crow bars which provide great mechanical advantage
cages
bars that block passages

[The Sideromancer]

Yes, you could make diamond objects. Yes, diamonds are brittle and flammable.

[ZZTRaider]

I think diamonds would fall under Major Creation as gems. In either case, they'd have a finite duration.

For bars, you'd probably want something like adamantine, but that only lasts 1 round per level.

Yes, you can make diamonds if you can make the appropriate skill check.
Now the problem is what is the appropriate check and the DC.

Probably it is something like a 400 DC profession Engineer skill check.
The appropriate tools add that +390 to the check that a good engineer need to make it in RL. But when you use magic you don't get the equipment bonus, so the skill check is almost impossible unless you have some huge bonus from some source.

Then there is what The Sideromancer said. Diamonds are hardness 10 on the Mhoss scale, but that only mean that they can scratch less hard materials, but that don't mean that they are hard to break.
To use common materials, glass has a hardness of 5.5, iron a hardness of 4. But if you use a hammer of glass on a piece of iron the glass hammer will probably shatter and the iron will surely suffer no damage.

A glass chain, while harder on the Mhos scale would be easy to break, a iron chain work way better.

I don't know, I've never made a chair free hand from a log, but a lot of wood rubbing has not done much (however i think a masterwork saw adds +2 to such a craft role) I think such spells have you make a craft role with magic, not just doing it by hand. Otherwise your going to have a whole lot of problems with casting fabricate to make a sword w/o a forge, or making anything with any of those spells really, pretty sure the DC starts with "have the tools required to do the job"

diamond is a poor building material because it is extremely brittle, like glass. it will never dent only crack, so any force capable of breaking it would actually be pretty low. Metals bend, it's why we make stuff out of metal and not bullet-proof glass.

[Ten'shun the Tengu]

Not to mention, what minor creation creates can't be used as a spell component.

Just, putting that out there.
