[QUOTE="Lefty, post: 143917, member: 2976"] My experience has been that cabbing and clear, colourless stones don't work well together unless you're happy with something that looks like a half a plain glass marble. Transparent stones can look good cabbed as long as they have plenty of colour or some kind of visual effect. I cabbed a piece of smokey quartz that looks ok like that but now I'm working on my first faceting attempt - a bit from the same piece of smokey - and it's only half done but it already looks better than the cabbed one. On that, rough2cut - what do you think is the best thing for polishing quartz (for faceting)? I'm buying a machine soon and have a bit of smokey and amethyst I wanted to start on. I'm polishing the bit of smokey at the club with a blue disc of very thin plastic that is apparently charged with ultrafine cerium. It's doing a good job but I'm told you can't buy them anymore. I'm also told that sometimes quartz doesn't like being polished with diamond. One of the machines I'm considering buying as a serious hobbyist is the VJ by Sapphire Engineering. Everyone I've asked about them seems to think they're the ducks nuts. Also, the little factory that makes them is only a couple of hours drive from where I live as opposed to being at the other end of the country or on the other side of the world. Is there any particular one/s you'd reccomend? [/QUOTE]
