A team of researchers has reported the first laboratory synthesis and recovery of bulk hexagonal diamond, a crystal form long predicted to be harder than the conventional gems used in cutting tools ...

A new form of carbon that rivals diamonds in its hardness, but has an amorphous structure similar to glass, has been produced under ultrahigh pressure in laboratory experiments. An amorphous diamond - ...

We’ve featured quite a few Diamond Select figures on our YouTube channel over the past year, and it looks like we aren’t going to be stopping anytime soon. The latest unboxing and review we’ve got for ...

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 ...

An amorphous diamond – one that lacks the crystalline structure of diamond, but is every bit as hard – has been created by a Stanford-led team of researchers. But what good is an amorphous diamond?
