What will happen if quartz is grinded with corundum?

+1 vote
What will happen if we grind the quartz crystal with natural corundum? Normally, corundum is harder than quartz, the quartz should be grinded away right? In return if the corundum is getting grinded and the suspected quartz crystal remains same, does it mean the other mineral is not quartz? But the specific gravity is is giving the valuses a value near to quartz.

Corundum is harder than quartz so the quartz would be abraded. Two distinct possibilities. The first is your corundum specimen is not corundum, second your quartz is not quartz but something harder. The only thing harder than corundum id diamond so your possibilities are limited.
