Thanks Makky
I have decided to do P5 P6 P7 first and then go around the edge with the frosted facets P2 P3 P4 after I have polished 5, 6 and 7. I am doing a fair sized stone but the frosted facets are still getting lost, doing the frosted after everything is polished might make them easier to see. (I hope).
It's one of those rare bits of Quartz that is polishing nicely with diamond, fortunately, nice crisp facet edges might make the frosted easier to do (redo)
