What can scratch diamond?
You can tell what Topaz can scratch by looking at the Moh's Scale of Hardness. It looks at ten well known, easily available minerals, and arranged them in order of their "scratch hardness". If a specimen to be tested can be scratched by a known mineral from the list, it is softer than that mineral. If it in turn will scratch another known mineral, it is harder than that mineral. Topaz is ranked an 8 and therefore can scratch everything lower than an 8. This includes quartz, feldspar, apatite, calcite, gypsum and talc.
