Mohs Scale of Mineral Hardness

Created by German geologist and mineralogist Friedrich Mohs, the Mohs scale determines hardness based on the ability of a harder mineral to scratch a softer mineral. There are other ways of judging hardness, but the Mohs scale continues to be used in the gemstone and mineral industry. Harder stones are best for jewelry that's designed to be worn often
