A diamond. Actually, a diamond can be scratched my other minerals.

Quartz is a mineral. No other minerals contain quartz.
Quartz is harder than apatite, quartz being a 7 on the Mohs mineral hardness scale and apatite being a 5.
Granite is an igneous rock. It is commonly formed from the following minerals. Quartz, potassium and Plagioclase Feldspars and Biotite Mica.
quartz
Quartz.
Fluorite with a Mohs hardness of 4 would be scratched by quartz (with a hardness of 7). Both calcite (Mohs hardness 3) and talc (Mohs hardness 1) are softer than fluorite.
