Yes. Corundum will scratch topaz and every other mineral with a hardness of 9 or lower on the Mohs hardness scale.
apatite will not scratch quartz topaz calcite or corundum
It can be scratched by a diamond, corundum, topaz, and quartz.
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.
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

feldspar, quartz, topaz, corundum, diamond.... Diamond will diffidently scratch glass its also made to cut glass if you get tech with it. (alyssamc6)
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.
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.
Anything under the 7 of the Moh's Hardness Scale, which is the number assigned to quartz. Minerals that can scratch quartz include topaz, corundum and diamond - pretty much everything else won't scratch it.
Corundum can scratch almost any mineral that isn't diamond.
