Updated and Extended Mohs Mineral Hardness Scale Chart

The Updated and Extended Mohs Mineral Hardness Scale Chart is used for determining the relative hardness of minerals. It helps in comparing the resistance of minerals to scratching and is often used in geology and materials science.

The updated and extended Mohs Mineral Hardness Scale chart is typically filed and published by the organization or institution responsible for compiling and researching mineral hardness, such as the Gemological Institute of America (GIA), mineralogy departments at universities, or geological research organizations.

FAQ
