Summary
I wanted a design that would look different. Something where I could leave an apex on the crown if I wished. The Mumble cut looks good either way.

Cutting Remarks

Mumble - tourmaline

An approximately 2.20-ct, 8.8 x 6 mm (deep) cornered Mumble cut, top-color pastel green tourmaline, Afghanistan. Cut by Jeff Graham.

Although the Mumble looks good with or without a table, I think cutting a table is a good idea with lighter colored and larger stones.

The Mumble isn’t hard to cut in larger stones, but the meets get difficult as the gem gets smaller on the crown.

This design cuts fast and works well in quartz, tourmaline, topaz, and peridot. I recommend cutting it in a medium-color material. Since this is a very bright design, it will overpower a lighter stone. (Still, I did cut the example shown above in a light pastel piece of tourmaline).

This is a “Money Cut.” I’ve found this shape sells very well for those of you interested. It will set easily in most trillion mounts, yet looks different enough to catch the eye. I’ve sold every Mumble I’ve cut.

Enjoy cutting your own “Mumble.”
