Diamond is the hardest mineral at Mohs hardness 10, ten being the hardest. There is no natural mineral substitute for processes requiring diamond. Diamond is four times as hard as corundum, the mineral constituting rubies and sapphires. Although diamond is the hardest naturally occurring mineral, it is easily fractured, a characteristic which allowed early jewellery makers to facet this crystal.
