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
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.
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 !
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.

Corundum and Diamond.
It can be scratched by a diamond, corundum, topaz, and quartz.

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 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.
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.
There are many minerals with hardness above 5.5 but the standard ones are feldspar,quartz, topaz, corundum and diamond.
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.
