by Arya Akhavan (September 2012)

This design was inspired by the thought of the sun rising through a Mayan temple. The facets on the 96 evoke stairs, leading to an archway at the top where the sun rises through. You may need to adjust angles for C9 and C10 based on your C7 step width. Works in materials from feldspar to CZ (RI = 1.52 - 2.16) with no changes. Suggested width = 8-12 mm
