I am also working on a great article about TEACHING THE NEXT GENERATION OF FACETERS. Previously I have taught people from all over the world from 16 years old to 80 years old how to facet. Recently my 11 year old granddaughter showed interest and I asked her if she’d like to try faceting. She cut a beautiful 12 millimeter amethyst with no more help than I’d give any student and was anxious to do more. I am going to teach her to cut a trillion for her second stone from lab created ruby...

Here is a picture of the SPLASH GUARD I use on all my machines.
