Ventilatore - Marco Voltolini

Citrine quartz featuring the "ventilatore" design

After looking at Van Sant's "Yin&Yang" (2-fold symmetry) and the "propello" design by Walt Heitland I found on the internet (3-fold symm), I decided that a 4-fold symmetry following this concept was worth a try. So here it is.

This design requires some care to get the right meetpoints, especially the first tier of the crown: there it is easy to overcut.

I decided to add a small table to avoid the "empty" spot in the light return pattern typical of some apex designs.

- Linguistic note: "ventilatore" is the Italian word for "electric fan".
