I don't think quartz is actually used, the minerals I have listed in my ingredients are the actual names of the minerals!
I think that would be very fun to go and search for quartz, I have some slabs of rose quartz but did not get them myself.
In all honesty, I know zero about how makeup is manufactured. From the name of your company, I wonder if actual quartz is used. Anyway, last week I was in New Hampshire and visited a mine that actually had pink quartz (rose quartz). At the mine, you can actually search for and keep the quartz you find.
