Additionally, carbon polymorphs even harder than lonsdaleite have been discovered in the crater.
Lonsdaleite has also been made artificially in laboratories.
Lonsdaleite occurs naturally in asteroids and cosmic dust and as a result of extraterrestrial impacts on Earth.
When viewed altogether, the atomic positions are the same as in lonsdaleite ( hexagonal diamond ).
Naturally occurring lonsdaleite has also been identified in non-bolide diamond placer deposits in the Sakha Republic.
It exists in various wurtzite BN modification is similar to lonsdaleite and may even be harder than the cubic form.
Consequently, it has been suggested that " stacking disordered diamond " is the most accurate structural description of lonsdaleite.
Lonsdaleite is simulated to be 58 % harder than diamond on the diamond's tip hardness of 162 GPa.
Lonsdaleite was first identified in 1967 from the Canyon Diablo meteorite, where it occurs as microscopic crystals associated with diamond.
:: According to " the stability domain of lonsdaleite ( hexagonal diamond ) lies entirely within that of cubic diamond ".
