Previously, the hardest diamonds known have been found only in asteroid and meteoroid impact craters. For instance, lonsdaleite was first discovered in the Canyon Diablo meteorite in Arizona in 1967.

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 first ultra-hard diamond was found in the Canyon Diablo meteorite in Arizona in 1967. Scientists have struggled to recreate lonsdaleite in the laboratory but now, a team of Chinese researchers ...

Some investments are “quite literally out of this world”, said ITV. Last week at Sotheby’s Dubai, a 555.55 carat black diamond called “The Enigma” was unveiled and it will become the ...

Lonsdaleite, also known as the meteoric diamond, was first discovered in 1967 and is formed from the impact of a meteorite hitting Earth's surface. Previously, lonsdaleite had only been found at ...
