Here is an uncut video of the process of preforming and cutting a gemstone that you can learn at the Institute of Gem Trading's Cutting and Recutting for Gem Business course.
This demonstration in Amethyst is done on a Sri Lankan style machine by a master cutter with years of experience. Can you match his speed and accuracy in your preforming and cutting?
