Quartz is definitely a bastard. The only thing that helped me was getting hold of a couple of lightning laps - https://lightninglap.com/ - the 3k resin bonded lap polishes like an 8k, and then a CeOx resin polishing lap from them.
I've never figured out how to get a satisfying polish with anything I have to apply to a lap, it just becomes scratch city.
Stone looks lovely though!
Thank you! I think I will try the Lightning Lap 3k, general consensus from everyone here is that 3k makes a difference.
I will say that the CeOx on Darkside is quite good, but it can't totally make up for a shit prepolish. If I can set it up for success with a better prepolish I think I'll be much happier with my process. Hopefully LL saves the day!
I've been so impressed with the LL pads that, outside of bonded cutting disks, I don't use anything else. Your milage may vary, though!
