While the girdle outline of this is derived from "Coruscating Dome 96", none of the rest of it is. The pavilion may be a bit tricky, but the crown is very easy, and the design itself sometimes has a bit of a Portuguese- style feel to it. Technically works in materials from quartz to CZ (RI = 1.54 - 2.16) with no changes, but I'd limit myself to 1.61 or higher. I'm planning to cut this in a yellow Djeva #131 synthetic spinel.
