Utopia – Cutting Remarks
Shown at left is a 18.3mm x 13.5 x 11.5 mm deep ~ 13.33 carat “Utopia” cut from flawless Brazil Citrine by Jeff Graham.
There is a real lack of high performance Barion pear designs available. I originally designed this because sometimes there is just no substitute for a large Barion Pear and I seem to have rough occasionally that just needs this type of design…
This is a very elegant pear to cut, but this design is not for new faceters. I added two (2) degrees to the pavilion tiers to cut this in Quartz, it makes a nice stone.
If you are cutting for the U.S.F.G. Single Stone Competition, be sure and read their specifications for both cutting and materials, before getting started…
I recommend that this design be cut on the larger side, at least 8mm wide, larger is better because of the very small angle changes on the pavilion mains ( P23, P24). On a small stone you can omit those facets and adjust the others to meet.
Cut it in refractive indexes 1.62 to 1.76 (84.3%) with no changes. I recommend a light to medium colored material. Note: The pavilion point may need tweaking in on a very large stone. There is an extremely minute chisel point (P19) that will not be apparent in most stones. Cut pavilion to center point.
Enjoy cutting “Utopia”… 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.
