I used to do a bit of lapidary ans siversmithing when I was younger. If your into making jewlery you might consider a modeling program. Making your own models is so much more rewarding and a heck of a lot cheaper. Check out some of the free ones, buy a copy of poser4. Learn the ropes and then go for poser 5 or one of the better 3d app. I don't use poser much, more of a 3d max fan myself, But I have made some nice money just making art and you can't beat that
