It may be true that diamonds are made of carbon, but saying that they are organic is false. What we deem as organic, at least in chemistry, actually means an organic compound. This means that carbon by itself (e.g. diamonds, graphite, etc.) is not organic, since it is composed of only one element.

But it should be noted that trying to delineate what is organic and inorganic have very arbitrary criteria. So just assume that any covalent compounds containing carbon is organic, and vice versa.
