Topaz has a hardness of 8 on the mohs scale.
A steel file has a hardness of 6.5, or maybe 7+ if it has been hardened.
In theory, the topaz is likely to be harder than the average steel file.
=== === ...you may want to avoid putting this to the test, because, although you might scratch the steel file with the topaz, you might also just damage your topaz in the process, because, who knows, maybe your steel file is made of best high-carbon steel, which has a hardness of 8 on the mohs scale!
And then there are steel files that have a layer of tungsten-carbide welded to the cutting surface. Tungsten-carbide has a mohs rating of 8.5 to 9! * For more information, see 'Related links' below this box.

What minerals can steel file scratch?
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.
Can calcite scratch other minerals if so which one?
No.because calcite is softer then feldspar
What mineral can scratch glass but can be scratched by steel file?
The mineral that can scratch glass but can be scratched by a steel file is quartz. Quartz has a hardness of 7 on the Mohs scale, allowing it to scratch glass, which typically has a hardness of around 5.5. However, a steel file, which has a hardness of about 6.5 to 7, can scratch quartz.
What will scratch calcite?
Using the Mohs Mineral Hardness scale, calcite has a hardness of 3. Hence anything with a hardness of 3 or above can scratch calcite (i.e...quartz and fluorite).
Can a paperclip scratch calcite?
No, a paperclip is not hard enough to scratch calcite. Calcite is a mineral with a hardness of 3 on the Mohs scale, while a paperclip is softer and would not be able to scratch calcite.

What is harder a steel file can scratch a penknife blade or calcite scratches a copper coin?
Calcite scratching a copper coin is harder because calcite has a higher Mohs hardness scale rating than copper. Steel files can scratch penknife blades because steel is harder than the blade material, which is usually softer.
Which object can scratch calcite but not apatite?
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.
What minerals can a steel knife scratch?
A steel knife can scratch minerals with a hardness lower than that of steel, such as gypsum, calcite, fluorite, and talc. Minerals like quartz, topaz, and corundum are harder than steel and cannot be easily scratched by a steel knife.
What mineral can scratch glass but can be scratched by steel file?
The mineral that can scratch glass but can be scratched by a steel file is quartz. Quartz has a hardness of 7 on the Mohs scale, allowing it to scratch glass, which typically has a hardness of around 5.5. However, a steel file, which has a hardness of about 6.5 to 7, can scratch quartz.

Can a paperclip scratch calcite?
No, a paperclip is not hard enough to scratch calcite. Calcite is a mineral with a hardness of 3 on the Mohs scale, while a paperclip is softer and would not be able to scratch calcite.
Can a steel file scratch muscovite?
Yes, a steel file can scratch muscovite because muscovite has a Mohs hardness of 2.5-3, while a steel file typically has a hardness of around 6.5. Harder materials can scratch softer materials according to the Mohs scale of mineral hardness.
What minerals can scratch a penny?
calcite
What mineral that can scratch gypsum but cant scratch calcite?
Between 2 and 3 because its hard enough gypsum but it can not scratch calcite because calcite is harder
