John F. Heusler G. G. designed these templates based on his artistic taste. He is an award winning jewelry designer and has been cutting gems for over 44 years. His articles in Lapidary Journal/Jewelry Artist Magazine the past few years showcase many of these cuts. Templates come in easy to use transparent 81/2 x11” plastic.
Use them to stencil your cab shapes onto slabs with a scribe before trimming.
