OK, OK, I've had so many people ask me for this design I've decided to put it online. I was going to keep my "Signature Series" unpublished and just cut them myself. Although I'll still keep some unpublished, I'll share some designs with my fellow faceters.

Cutting Remarks

The Signature #4 works great with light-colored materials, especially aquamarine. This design has surprising reflections that help improve color and make the stone interesting. Also, it's fast and easy to cut, which never hurts.
