NEW! - Mohs' Top 10Story
In the early 1800s, German mineralogist, Friedrich Mohs, created a rockin’ way to test a mineral’s hardness on a scale of 1 to 10. This “Mohs Hardness Scale,” helps to identify minerals based on how easy, or hard, they are to scratch with these ten common reference minerals. We like to think of the Mohs Hardness Scale as the ‘Rock, Paper, Scissors’ of the mineral world. Gypsum is soft, but it covers talc. Corundum cuts apatite, but is smashed by diamond. A good hammer beats them all, mind you. Mohs yeah!
