der Standard DEA Chinese research team was able to clear out some persistent doubts about the existence of the Lonsdaleit mineral, which arises from meteorite impacts
Long considered as a simple geological artifact or a laboratory myth, the hexagonal diamond has just made a noticeable entry into the real world, potentially forging a new standard of hardness.
Researchers create pure hexagonal diamonds that are harder than natural diamonds
Diamonds are famous for their strength, but scientists have long suspected that another form of diamond might be even harder. Evidence of this was gathered over the past sixty years in meteorite fragments, where the mineral lonsdaleite appeared. Lonsdaleite was theorized to have formed due to immense impact pressures on carbon-rich rocks from cosmic impacts. However, the evidence supporting this theory has generally been inconclusive due to its …
