Machining Of Industrial Sapphire

Lapidary Fundamentals: Cabochon Cutting

Once you have the outline shaped, you'll start the process called "peeling the apple." Grind a bevel all the way around the gem at about 45 º, bringing it 2/3rd to 3/4th of the way down to the bottom. Then, grind another bevel, all the way around the stone again, at about 60 º. Leave some of the previous cut showing.
