Diamonds are carbon, just like coal. It takes a bit more to get them burning and keep them burning than coal, but they will burn, as numerous YouTube demonstrations will attest. The trick is to create the right conditions so that a solid diamond can react with the oxygen required to fuel a fire.
[...] When first heated, a diamond will glow red, then white. The heat enables a reaction between the surface of the diamond and the air, converting the carbon to the colorless and odorless gas carbon monoxide (a carbon atom plus an oxygen atom).
"The carbon plus the oxygen to make carbon monoxide generates heat; the carbon monoxide reacting with the oxygen generates more heat; the rising heat causes the carbon monoxide to move away, so more oxygen is brought in," he told Live Science.
[...] That fire, however, will amount to only a glow. Nurturing a flame on the surface of a diamond usually requires an extra boost: 100% oxygen rather than room air, which is only 22% oxygen. This increase in concentration gives the reaction all that it needs to self-perpetuate. The carbon monoxide rising from the diamond ignites in the presence of oxygen, creating a fire that seems to dance on the stone's surface.

We saw an educational film in high school chem. One of the things they did was heat up a diamond with a torch, and drop it in liquid oxygen. IIRC, It didn't explode or burn with a flame, but it kind of sizzled around and obviously broke into two pieces which continued reacting.
I'm not sure if this was the same film where they worked down a group 1 of the periodic table starting with sodium in water. The reactions became increasingly violent, and the final entry, Francium, exploded the reaction vessel. I wonder if that was planned. I'd love to see that again, in all its herky-jerky, poorly colored educational film glory. It'd be a good trip down memory lane.

Francium is the last one, but you can't do it due to scarcity and radioactivity, so the last element in the film must have been cesium. I should have googled fore the film before I hit send. It doesn't seem to be out there.

I seem remember that same film, which resulted in us making various jokes about getting our hands on some elemental cesium for the rest of the school year. Luckily for perhaps everyone, there wasn't anything like that in the chemistry lab at school, though there was a small jar with some elemental sodium submerged in oil that our teacher showed us, but wouldn't let us open.
On a related note, this [youtube.com] is probably my favorite film on the subject, which really goes to show that there was very different attitude towards the environment in the earlier part of the previous century.

I wish I had so many diamonds that I needed to find a way to burn some. OTOH generating more atmospheric CO2 seems to be a foolish thing to do in this day and age. I have often wished there were easy ways to accomplish the reverse process - take atmospheric CO2 and convert it to diamond and atmospheric O2. Then that sequestered carbon could be buried in a hole somewhere - maybe South Africa.

Considering the cost of electricity, microwave, "seed diamond", etc. DYI isn't really an option here, unless you just really want to "make a diamond". Even then, you're only adding to an existing diamond. The process is interesting though.

Class action lawsuit for false Adverting, anyone?. May a few industrial diamonds in payment. Also known as crushed diamonds. They are no longer looking for large multi-carrot diamonds. Dig under the field, place a rock crusher and make the field "flow" into the crusher and pipe the dust / slurry to surface for extractions. Cost effective.

LOL... Multi-carrot?
Is that for a Bugs Bunny style wedding ring? :)
I think you mean carat, a unit of mass equal to 0.2g, rather than a tasty (typically orange, white or purple) root vegetable.
When I was a kid I ate so many carrots that I started turning orange from the excess β-Carotene and my parents had to cut me off for a couple weeks and I had to tone down my carrot consumption... Sniff, sniffle... :)
On the plus side, 4 decades later, I still have significantly better than 20/20 vision (and excellent night vision, no halos, etc.) The last time I had an eye exam, it was still well under 20/10.

Hmm, I think I read a story once where someone illustrated the extreme wealth of one of the characters by remarking they had lump diamonds in a coal scuttle instead of coal. It looks like that might not work. If I recall correctly, anthracite needs to be placed in a hot fire to burn, so railway engines required their fires to be started with softer coal first, and once the fire was sufficiently warm the fireman could start shovelling anthracite on it. Perhaps diamonds are the same - put in a hot fire, they might burn as described.
