Theoretical calculations suggest that HD [hexagonal diamond] may even surpass cubic diamond (CD), the hardest and least compressible material known in nature today. Theoretical calculations ...

By adjusting the parameters of their setup, the researchers found they could get the graphene to grow into a synthetic diamond with hexagonal lattices. The first diamond made by the group was ...

By subjecting graphite to extreme pressure and heat, researchers synthesized a rare hexagonal diamond, also known as lonsdaleite—a crystal structure that has long been theorized to be stronger ...

The synthetic hexagonal diamond exhibits high thermal stability up to 1,100°C and a hardness of 155 GPa, promising advancements in aerospace and defense industries. Chinese scientists develop ...

The result was a breakthrough in creating hexagonal diamonds in a controlled setting, as opposed to the traditional cubic structure. "There is a natural way to create [this kind of] diamond ...
