0.04% of the Earth's atmosphere is Carbon dioxide. Of this, 33% is actually carbon - the rest is oxygen. (There're traces like Carbon monoxide and petrol vapours, along with carbon particles themselves, but let's assume carbon dioxide alone)
So, that's about 0.0132%. Okay, Lets be generous and call it 135, to account for the rest.
So. For every kilogram of air we draw in, 0.0135% will be carbon we can use. That's about .135 of a gramme
We need 200 mg for one carat.... so about 1.5KG of atmosphere per carat, if I've done this right. But that seems very, very wrong somehow. Because that's about 1.5 cubic metres of air, or thereabouts. That really can't be right.
