Diamonds: precious stones and some of the hardest material on Earth, they are not only pretty to look at, but they are useful in industry and science. To make them, one has to apply high temperatures and pressures to carbon molecules such as graphite. A recent result published in the journal Nature described how researchers could generate custom-made diamonds three to four nanometres in size, whereas a human hair is 80,000 to 100,000 nanometres thick.
