Diamond is the hardest mineral and is the only one that can scratch corundum. but in my opinion corundum will scratch corundum any mineral of the same hardness will scratch the other !

What are some uses for Corundum?
Corundum is very hard. It serves as the index mineral with a hardness of nine on the Mohs Hardness Scale. It is the third hardest mineral known, with diamond and moissanite being the only minerals with a greater hardness. This high hardness makes corundum especially useful as an abrasive. Crushed corundum is screened to produce uniformly-sized grits and powders. These are used as grinding media and used to manufacture polishing compounds, sand papers, grinding wheels and cutting tools. The costs of manufacturing abrasives have been declining through innovation. Synthetic corundum is increasingly being used as an abrasive instead of natural corundum.
Is corundum hexagonal or cubic?
Corundum ( (Al_2O_3) ) is hexagonal in crystal structure.
How do you make synthetic corundum?
There are several different methods, your best bet would be to expose powdered aluminum and a small bit of chromium to the open flame of a blow torch. You may need to use something hotter, as the heat required to fuse the powered aluminum to the chromium is around two thousand degrees Celsius. You can buy synthetic boules of corundum online for pennies a carat. As product of the chatum method, there are now synthetic crystals on the market, in the form of hexagonal/water worn crystal pieces. The best of luck.
