Signature #4 (Radiant Trillion) - Cutting Remarks
Shown at left is a 10.5mm x 7mm deep ~ 3.64 carat Signature #4 cut from Top Zambian Aquamarine by Jeff Graham.
Ok, ok, I have had so many people ask me for this design, that I am going to put it online. My “Signature Series” of designs are all ones I was going to keep unpublished and just cut myself. I will still keep some of them that way. But I will share some with my fellow faceters... There is a design in my “Money Cuts # 4” that is actually a modification of this design and pretty close. But people keep asking my for this exact one, so here it is...
This is a great design light colored materials (about my favorite), especially Aquamarine. There are surprising reflections that help improve color and make the stone interesting. This is also fast and easy to cut, which never hurts.
Enjoy cutting your "Signature #4"... Drop me an email to let me know your results and what you've cut, or feel free to inquire if you have any questions or need some help regarding this design.
