What is the only mineral that can scratch 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 !
What mineral can scratch quartz but cannot scratch 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.
Can corundum scratch topaz?
Yes. Corundum will scratch topaz and every other mineral with a hardness of 9 or lower on the Mohs hardness scale.
Can quartz 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.
Can corundum be scratched by a nail?
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.

An unknown mineral scratches apatite and is scratched by corundum. What can you conclude about this mineral and hardness?
The unknown mineral has a hardness greater than that of apatite (which has a hardness of 5 on the Mohs scale) since it can scratch it. However, it has a hardness less than corundum (which has a hardness of 9) since it can be scratched by it. Therefore, we can conclude that the hardness of the unknown mineral is between 5 and 9 on the Mohs scale.
Is corundum harder than diamond?
No. Diamond is the hardest mineral. It measures 10 on the Mohs scale: Corundum measures 9, which is less hard than diamond, as below.
