[QUOTE="Lefty, post: 239415, member: 2976"] Yep. I like the finish left by oxides but still found diamond faster on topaz. Maybe if you want to be really pedantic you could give it a final tweak with alumina after polishing with diamond. I had no success polishing garnet with alumina until it was pointed out that I was using alumina B (0.05 micron) which is very much finer particle size than alumina A (think it's 0.3 micron). I then tried A which seemed to work a lot better. [/QUOTE]
