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

I'm not a very big fan of keeled designs, but this crown design kinda forced my hand. It turned out pretty nicely, though - the stone has great light return, an interesting reflection pattern, and it's decent for recutting spinels and corundum. Works in any material from quartz to rutile (RI = 1.54 - 2.62) with no changes. Suggested length = 6-10 mm
