dave yup the whole thing comes down to YOU to do the faceting, the machine is just a tool for holding and guiding. use your eyes. the machine can set angle and index but how far you cut, i haven’t found any machine with an absolute stop where everything meets exact. in 68-77 while working at crystalite i was a a big show in Wa. D.C. where a woman won the faceting trophy, the stone was accurate and beautiful and she was totally blind. figue that one out. it wan’t the stops. gemmakermz@cs.com
