Diamonds are proven to scratch all minerals including itself.
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.
A steel file can scratch minerals with a hardness of 6.5 or lower on the Mohs scale. This includes minerals such as gypsum, calcite, and fluorite.
Yes, other minerals can scratch hematite. Hematite has a hardness of 5.5-6.5 on the Mohs scale, so minerals with a higher hardness (like quartz or corundum) can scratch hematite.
The scratch table is called the Mohs Scale of Mineral Hardness and measures the hardness of minerals in relation to the known hardest (diamond) and softest (talc) minerals.

Diamonds are proven to scratch all minerals including itself.
Diamond is the hardest naturally occurring mineral and can scratch all other minerals. Talc is the softest of minerals and cannot scratch any other mineral.
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.
A steel file can scratch minerals with a hardness of 6.5 or lower on the Mohs scale. This includes minerals such as gypsum, calcite, and fluorite.
Talc is the softest mineral on the Mohs scale with a hardness of 1, so it can be easily scratched by harder minerals. Talc can scratch over minerals with a lower hardness value, but it cannot scratch minerals that are harder than itself, such as quartz or diamond.
Yes, other minerals can scratch hematite. Hematite has a hardness of 5.5-6.5 on the Mohs scale, so minerals with a higher hardness (like quartz or corundum) can scratch hematite.
The scratch table is called the Mohs Scale of Mineral Hardness and measures the hardness of minerals in relation to the known hardest (diamond) and softest (talc) minerals.

Yes, quartz is considered a hard mineral ranking 7 on the Mohs scale of hardness, making it able to scratch most other minerals. However, there are harder minerals such as diamond and corundum that can scratch quartz.
