Tessellation 20

by Arya Akhavan (November 2012)

I was stuck in MSP overnight, from 8PM to 6:30 AM, and had nothing better to do than watch anime and write interesting faceting patterns. This is an extremely easy design to cut, with a fast pavilion and a simple crown, and the apex not only makes it easier but gives it surprisingly good tilt performance. Works in materials from quartz to rutile (RI = 1.54 - 2.62) with no changes, but I like it best in yellow zircon or smaller sapphires.
