I know that Diamonds are the hardest substance known to man, but what's the hardest stuff we can make?

Man can make synthetic diamonds in a lab using intense heat and pressure, synthetic and more expensive to make than finding them, but diamonds nonetheless.

Man-made diamonds are made in hydraulic presses that mimic the pressures needed to create diamonds. There are several grades of man-made diamonds. Lower-quality diamonds are used for cutting tools and tools to sharpen metal. Higher quality diamonds are used in jewelry. Because of the very regular disbursement of pressure on the carbon in diamond presses, man-made diamonds are perfect or very near perfect gems. Natural diamonds are not, as the pressures in the Earth's crust are often uneven. Thus, natural diamonds have small imperfections and occlusions. In fact, the only way a jeweler can tell the difference between a natural diamond and a man-made diamond is that the man-made diamond is too perfect!

Diamond is the strongest substance that mankind can produce.Synthetic diamonds are perfect and so are used in the jewelry industry whereas less perfect are used for cutting metals or coating metals and other associated industrial used implements.Naturally produced diamonds are most commonly less perfect due to constant changes of pressure and difference of pressure equilibrium within the earths crust.Some of the best naturally made diamonds on earth are associated with Kimberlites.

When I left the stuffing dish in the over the other day and forgot it, the bit left in the bottom turned into some industrial strength charred substance that was quite probably the hardest thing in the known universe.

Diamonds are hard, indeed. And man can really manufacture them today. But if it is a question about strength, carbon nanotubes (= artificial layer of carbon atoms, having covalent bonds with every neighbouring carbon atoms) are strongest.

cant we make diamonds too? they dont look the same as the sparkly diamonds that we buy but they have the same structure and are made of the same stuff

Diamonds. They can be man made, search google for man made diamonds.

Artificial diamonds, used in industry for polishing and grinding.

Sorry that question could be taken in a different way thinking you said 'what is the hardest thing a man can make' don't you think that sounds a bot wrong!!
