Summary

Story summary

Scientists have synthesized a sizable meteorite diamond called lonsdaleite, potentially harder than traditional diamonds.
High-pressure, high-temperature methods were used, inspired by the Canyon Diablo meteorite.
Initial tests indicate lonsdaleite's toughness matches that of regular diamonds, with various industrial applications.
Future research aims to create larger, purer samples for practical use within the next decade.
