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 ...

Scientists have created the first sizable meteorite diamond — also known as lonsdaleite or hexagonal diamond — a material predicted to be even harder than the diamonds normally found on Earth. The ...

Researchers have synthesized millimetre-scale hexagonal diamond, a crystal structure so elusive that many physicists doubted it could ever be produced in bulk. The material, also called lonsdaleite, ...
