I was in the mood to write trillions, and here's yet another one of the things I came up with. It's got a bit of a weird pavilion sequence, and the crown corners are a bit annyoing to cut cleanly, but it performs very well. Works in materials from quartz to sphene (RI = 1.54 - 1.88) with no changes, but I prefer tourmaline. Suggested size = 6-10 mm
