This design is an expansion of the previous Tessellation's crown, continuing with the theme of pentagons and broken rhombi. I have a strong feeling that if I try to expand one tier out, I'll need to switch to a 120 index. Works in materials from beryl to rutile (RI = 1.58 - 2.62) with no changes, but I prefer it in peachy zircons. Suggested size = 8-12 mm
