Hexagonal diamonds are formed when graphite is subjected to strong impact and heat, such as due to a meteorite impact. While ordinary diamond has a structure called cubic, hexagonal diamond is ...

In chemistry, structure is everything. Compounds with the same chemical formula can have different properties depending on the arrangement of the molecules they’re made of. And compounds with a ...

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 ...

Chinese scientists have successfully developed a high-quality “super diamond” in the laboratory, exhibiting a hardness far greater than natural diamonds. This breakthrough holds significant industrial ...

Researchers have succeeded in creating a rare type of diamond, known as lonsdaleite or hexagonal diamond. This material, whose hardness could surpass that of conventional diamonds, opens new ...
