Cabochon Cutting II

by John Rasmussen on June 29, 2009

I have taken on another round of cutting stones (cabochons this time). A friend on the About.com Jewelry Making forum provided me with three rocks from California a while back to identify for her. So I have take a slab from each of them, a breccia from Florida (courtesy of Carolee) and a green beryl (emerald) that Debbie and I found in North Carolina. Cut them with the trim saw, the to the grinding drum (80 grit diamond) to form the general shape (preform) that I want to end up with. You can see on the pudding stone that I (or maybe the stone) have changed my mind as to the shape. Next step is to put the stones on dops and start using the lapidary to shape/polish the stones. Here is the preform step:
