[QUOTE="fossickeract, post: 343793, member: 3672"] Hi Donna, I have two suggestions firstly I do an 8000 prepolish using a ceramic lap found the harder lap does a better job with sapphire. The ceramic is different to use but very good once you get the hang of it. If you get hold of one I could provide detailed instructions for successful use. Polish I use 100,000 on a typemetal lap and it works well on sapphire. I have found recently that diamond paste purchased in a syringe has been a bit suspect so have gone back to mixing my own.[img]https://www.prospectingaustralia.com/forum/img/member-images/3672/1499147980_gg_party_sapphire_without_dust_2-optimized.jpg[/img] Bit of dust but no scratches on this Grabben Gullen party.
