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

After decades of debate, researchers say that they have found the clearest evidence yet for this rare form of carbon ...

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 ...

Scientists have discovered that an ancient "catastrophic collision" between a dwarf planet and an asteroid is responsible for the creation of a rare and mysterious cosmic gem. The findings, published ...

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 ...

“These findings resolve the long-standing controversy on the existence of hexagonal diamond,” researchers said.

After decades of chasing after a rare hexagonal diamond, a Chinese team says their iteration of the elusive material is the ...

New research indicates that a rare form of diamond may originate in the burbling cores of distant worlds, arriving on Earth thanks to violent cosmic collisions. According to a team of scientists in ...

To misquote a famous song, "Diamonds are industry's best friend." Cubic diamond is the hardest mineral on Earth and is used in everything from precision cutting tools to high-performance ...

Scientists have detected the presence of a rare "folded diamond" that arrived on Earth from outer space via an asteroid. The material found is known as lonsdaleite, and like a diamond, it's made out ...

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