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.
