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 !
According to the Mohs scale of mineral hardness, quartz (7) will not scratch any mineral with a higher number on the scale. Corundum is listed at 9. Therefore quartz will not scratch corundum, but corundum can scratch quartz.
apatite will not scratch quartz topaz calcite or corundum
no it can't
Yes. Corundum will scratch topaz and every other mineral with a hardness of 9 or lower on the Mohs hardness scale.
bacially it has a hard harness.
Corundum can scratch almost any mineral that isn't diamond.

Corundum and Diamond.

Fluorite is unable to scratch feldspar, quartz, corundum, diamond, or any other mineral with a Mohs hardness greater than 4.
I would guarantee that diamond would scratch it, and types of corundum like rubies, sapphires and raw corundum probably would, because it is 9 on the moh's scale of hardness. Quartz, emerald, agate and topaz would also scratch it.
A diamond has a hardness of 10 on a scale of 10 known as Mohs Hardness Scale. A diamond can scratch any other mineral. It isn't the only mineral that can scratch glass thou, quartz, corundum,garnet, among others
Minerals that will scratch apatite must be more than a 5 on the Moh's hardness scale. So feldspar, quartz, topaz, corundum, and diamond will scratch apatite.
