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
Topaz is a mineral that can scratch quartz due to its hardness of 8 on the Mohs scale, while corundum, with a hardness of 9, cannot be scratched by topaz. This places topaz in between quartz and corundum in terms of hardness, allowing it to effectively scratch quartz but not 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.
Corundum can scratch all minerals except diamond, making it the second hardest mineral on the Mohs scale with a hardness of 9. Diamond, with a hardness of 10, is the only mineral that can scratch corundum.

Corundum and Diamond.

The unknown mineral would be topaz. Topaz lies between apatite and corundum on the Mohs scale, making it capable of scratching apatite and being scratched by corundum.
No, corundum is a very hard mineral, scoring a 9 on the Mohs scale of hardness. A fingernail typically ranks around 2.5 on the scale, so it would not be able to scratch corundum.
Diamond is the only mineral that has the same hardness as corundum, which is the second hardest natural mineral on the Mohs scale after diamond. Both corundum and diamond have a hardness of 9 on the Mohs scale.
Fluorite is unable to scratch feldspar, quartz, corundum, diamond, or any other mineral with a Mohs hardness greater than 4.
