Designed for Greensboro Gem & Mineral Club. For their 2004 Faceters Engagement Calendar project.

I enjoy the Greensboro Gem & Mineral Club Faceters Engagement Calendar project because it forces me to think creatviely. Here is a Navette which literally means "little boat". I calculated angles for quartz but it should work universally.
