bacially it has a hard harness.
apatite will not scratch quartz topaz calcite or corundum
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 !
Minerals that can scratch apatite include fluorite, quartz, topaz, and corundum. These minerals have a higher hardness level than apatite on the Mohs scale, which allows them to scratch apatite.
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.
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.
apatite will not scratch quartz topaz calcite or corundum
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.

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.
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.

It can be scratched by a diamond, corundum, topaz, and quartz.
Corundum and Diamond.
No, corundum cannot be scratched by diamond. Diamond is the hardest known mineral on the Mohs scale, ranking at 10, while corundum ranks at 9. This means that diamond can scratch corundum but not vice versa.
no it can't
On the Mohs mineral hardness scale, calcite is about a 3, and apatite is about a 5. So, whatever is at a hardness of 4 will scratch a 3 but not a 5. That mineral is fluorite.
