Cutting Remarks

Cornered - Nigerian rubellite tourmaline

A 9.07-ct, 13.5 x 8.6mm deep Cornered, cut from top Nigerian rubellite tourmaline by Jeff Graham.

Cornered is a “Money Cut.” You can facet it quickly and easily. Plus, it performs very well. Checkerboard designs generally sell well, too, so I’m always looking for new ways to cut them.  

I wanted something that would work well with saturated material, like the Nigerian rubellite in the photo. This stone was just too dark and too big for a regular checkerboard. My design also makes a good choice for a beginner’s cut, especially for someone who hasn’t tried a checkerboard yet.

As the stone gets large (over 8 mm), especially in lighter colored material, I recommend cutting a table to meet C4.

Enjoy cutting your own Cornered.
