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 ...
