Suite: Tessellation Party! by Arya Akhavan (October 2012)

This F-type pattern has a bit of a slow, laborious pavilion, but has impressive light return and play of light. The crown is very interesting as well, hosting squares and triangles very cleanly. This design works best in rhodolite garnet, but can be cut in materials from feldspar to rutile (RI = 1.52 - 2.62) with no changes. Suggested length = 7-12 mm
