A team of researchers from Jilin University and Sun Yat-sen University in China has successfully synthesised a lab-grown version of Lonsdaleite, a rare carbon allotrope. Their findings, published in Nature Materials, indicate that this artificial form of Lonsdaleite is at least 40% harder than natural diamond.What is Lonsdaleite?Lonsdaleite, named after the British crystallographer Professor Dame Kathleen Lonsdale, was first identified in 1967 within the Canyon Diablo meteorite in Arizona, USA. Unlike conventional diamonds, which have a cubic crystal lattice, Lonsdaleite has a hexagonal structure, contributing to its extreme hardness.
