You can find cutting instructions for the Tic Tac here.
Note that I have large, distinctive facets on the crown. These create the “X” of the Tic Tac. I did this because as the stone I was cutting got darker, the more the reflection from the surface of the facet(s) tended to show. Instead, I wanted an interesting design to show on the crown.
I designed this cut for some dark blood-red garnets. These have come out of Africa lately. The finished stones show a lot of sparkle.
In 6-8 mm sizes, the Tic Tac makes an excellent earring design. On a very small stone, you can skip the P5 tier.
Enjoy cutting your “Tic Tac.”
