Diamonds are famous for their strength, but scientists have long suspected that another form of diamond might be even harder.

Researchers have synthesized millimetre-scale hexagonal diamond, a crystal structure so elusive that many physicists doubted ...

A Chinese research team has produced bulk hexagonal diamond, a crystal structure long theorized to be harder than ...

The diamond was around 0.04 inches in size and exhibited more sturdiness and resistance compared to typical cubic diamonds.

Researchers made small, pure samples of the elusive mineral lonsdaleite – also known as hexagonal diamond — and tested its ...
