Lonsdaleite and Mineral Properties

The video explores the hardness of diamonds, traditionally considered the hardest mineral, and introduces lonsdaleite, a potentially harder mineral found in meteorites. It explains the Mohs hardness scale, the role of chemical bonds and lattice structures in determining hardness, and the challenges in studying lonsdaleite due to its rarity. The video also discusses ongoing research to synthesize lonsdaleite and its potential industrial applications. Sponsored by Wondrium, the video highlights educational resources available on minerals and geology.

What is the Mohs scale used to measure?
