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. For example, a diamond (hardness = 10) will scratch garnet (hardness = 6.5-7.5), but not the other way around. Therefore, a diamond is harder than garnet. Harder stones are best for jewelry that's designed to be worn often. There are other ways of judging hardness, but the Mohs scale continues to be used in the gemstone and mineral industry.
