Corundum crystals belong to the ditrigonal-scalenohedral class of the trigonal symmetry D63d - R 3-C(L33L23PC) with symmetry elements:
• Mirror-turn axis of the sixth order (ternary inversion axis)
• Three axes of the second order normal to it
• Three symmetry planes normal to the axes of the second order and intercrossing
along the axis of the highest order
• Symmetry center

Which is the hardest mineral?
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.
What is the sapphires crystal shape?
a oval
