Web12 mrt. 2024 · The Mohs hardness scale. It’s vital to understand that the Mohs scale is not a linear scale.Instead, it ranks minerals on a relative scale based on their scratch hardness, so although corundum (ruby or sapphire) is a 9, a diamond at 10 is almost 5 times harder (according to Vickers Absolute Hardness Scale) and 3 times harder … Web10 apr. 2024 · Most fall within a range. For instance, tourmaline is ranked Mohs hardness 7.0 to 7.5. Garnet is ranked 6.5 to 7.5. Hardness Scale Hacks. Most trained geologists have “hardness picks” – special pencil-like tools crafted around the Mohs Scale. These picks help them to make a preliminary evaluation of minerals in the field.
