Mohs Hardness Scale

A scale for measuring the relative hardness of a mineral by its resistance to scratching, ranging from 1 (talc) to 10 (diamond).

Part of speech: noun
Definition: The Mohs Hardness Scale is a method used to compare the scratch resistance of minerals or gemstones, serving as a pivotal tool in identifying and categorizing them based on their physical properties. Created by Friedrich Mohs in 1812, the scale assigns a hardness level between 1 and 10 to a mineral, with 1 being the softest (talc) and 10 the hardest (diamond). This scale is instrumental in the jewelry industry, as it influences decisions regarding the cutting, setting, and care of gemstones to ensure their longevity and preservation. The relative hardness determined by this scale aids in discerning the suitability of a gemstone for specific types of jewelry, where a higher Mohs scale rating signifies a gemstone's capability to endure more wear and tear, making it an ideal choice for pieces intended for everyday wear.
