Mohs hardness is a measure of the resistance of a mineral to scratching or abrasion, based on a scale of 10 minerals with different hardness. Learn how to rank the hardness of minerals, gemstones and everyday objects using the mohs hardness scale, developed by friedrich mohs in 1812. Citrine is a variety of quartz with a hardness of 7 on the mohs scale. Find out the hardness values of opal, diamond, quartz, and other common substances. Learn how to rate the hardness of minerals and materials using the mohs scale, a qualitative test based on scratching. Find out which substances are harder than diamond and how to perform the simple scratch test. The mohs hardness scale is a set of ten reference minerals (numbered 1 through 10) that are used to determine the relative hardness of minerals and other objects. Learn how to measure the relative hardness of minerals using the mohs' scale, which ranges from 1 (talc) to 10 (diamond).
