Chinese Checker - Cutting Remarks Shown at left is a 9.2 x 7.9mm deep ~ 6.49 carat Chinese Checker cut from flawless Rose Malaya Garnet by Jeff Graham.
I wanted to design something that had a high light return, like a round brilliant, but that would have a very square outline. A lot of square designs do not have much appeal because they are just not very bright or distinctive. I think that “Chinese Checker” pretty much takes care of these issues. It cuts well in Garnet, Quartz, and Tourmaline, with no changes. It works best in a medium to light colored material and will darken a fair amount, because of it’s depth.
Enjoy cutting your "Chinese Checker"... 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.
