MOHS Hardness Scale For Gemstones. The MOHS Hardness Scale starts with talc at 1 being the softest mineral and ending with diamond at 10 being the hardest mineral. It is universally used around the world as a way of distinguishing minerals. Simply put: the higher the number, the harder the mineral. The MOHS scale …
The Mohs scale is a system used to rank materials on their hardness, which is graded using numbers from 1 to 10. It can be used to compare gemstones, metals and other materials, and evaluate their relative durability. Where a metal stands on the Mohs scale indicates which other metals can scratch it. For example, gold's hardness rating is 2.5 ...

12-12-2019· The Mohs Hardness Scale developed by Friedrich helps you decide the strength and hardness of any material or mineral. The more you move up the scale (1-10), the minerals become harder and harder. On the other hand, the below you go, the mineral becomes softer and softer, ending with the softest mineral.
De hardheidsschaal van Mohs is een schaal van 1 tot 10, die de relatieve hardheid van een mineraal aangeeft. De hardheid kan bepaald worden met een sclerometer.De schaal werd in 1812 ontwikkeld door Friedrich Mohs (1773-1839). Hardheid valt te bepalen door te zien welke stof de andere een kras kan toebrengen. De hoogste waarde is 10, die wordt toegekend aan diamant.
