Recently, Australia's Monash University, Australia's Commonwealth Science and Technology Organization (CSIRO), and the Royal Melbourne Institute of Technology (RMIT) have jointly confirmed the existence of superhard diamonds in dwarf planets. The research was published in the Proceedings of the National Academy of Sciences (PNAS).

Lansdaleite is a rare hexagonal diamond that is harder than the more typical cubic structure and can be used to make superhard device parts. The scientific team used a series of cutting-edge scientific techniques to study the largest sample of the ureleite meteorite to date. They used an electron probe microanalyzer to map the relative distribution of graphite, diamond and lansdaleite in the sample, and used a high-resolution transmission electron microscope (TEM) with an identification accuracy of 1 micrometer to confirm the lansdaleite. clear evidence.
