Nano-material is harder than diamonds By Will Knight A material that is harder than diamond has been created in the lab, by packing together tiny ânanorodsâ of carbon. The new material, known as aggregated carbon nanorods (ACNR), was created by compressing and heating super-strong carbon molecules called buckyballs or carbon-60.
To summarize Ankit and Mads's answers: it depends on what strength you are looking for. Some people are interested in hardness. Diamond is the hardest substance discovered to date, but note that hardness here refers to scratch resistance. Diamond can be shattered quite easily; if you could obtain a sheet of diamond and hit it, it would break like glass. In other words, you probably wouldn't want to make a diamond car or building.
