Hi all. I did a degree in jewellery 20 years, and just getting back into it. However, I never really spent much time on setting stones. So… the first cabochon setting i tried, ended up marking the stone. I've looked at the forum and can't find the best way to polish up dull stones. There was mention of Polygold 2000, but couldn't find it for sale. Any advice? I have a pendant motor, and a desk polishing motor with mops, so i guess i just need to know what polish to use. Thanks so much
