In 1822 German mineralogist Fredrich Mohs composed a scale detailing the hardness of gemstones. The scale details 10 minerals ranked in order of their ability to visibly scratch one other. Position 1 is the softest and 10 is the hardest.
Diamond is positioned at 10 and is infact many times more durable than any other gemstone. This is because diamond is held together by by extremely strong chemical bonds.
