Little Different - Cutting Remarks

Tourmaline cut by Tony Carson

Little Different - Cutting Remarks
Shown at left is a 11mm x 7.3 mm deep ~ 4.32 carats

This is a round brilliant done on an odd 77 index. I originally designed this cut when I bought a 77 index from Ultra Tec, around 1996.

I was going to put this design on a t-shirt, but decided not to because only Ultra Tec owners could get a 77 index at the time. That has changed because there are others making a 77 index now.

This design is one of the best odd symmetry designs I have ever seen and is a very good example of what can be done with odd indexes.

This cuts well in about any material, I prefer it in light to medium saturation. Cut in refractive indexes 1.54 to 1.93 with no changes.

Enjoy cutting your "Little Different"... Drop me an e-mail 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.
