■ Mohs hardnessWhat is

A measurement standard for comparing the hardness of gemstones devised by German mineralogist Friedrich Mohs. Most widely used around the world. Morse listed 10 well-known minerals in order of their ability to scratch. Barrels with a hardness of 1 are the softest and will scratch when rubbed against all harder (higher hardness) stones. Our fingernails are 2.5 on the Mohs hardness scale, and window glass is 5.5. A diamond with a hardness of 10 is the hardest and scratches all other stones when rubbed together. In terms of pure hardness, diamond has a hardness of 8000, while corundum with a hardness of 9 on the Mohs scale has a hardness of 2000, and quartz has a hardness of about 800. You can see how hard a diamond is.
