For some reason, I was in the mood for trillions, so I wrote three of them, each one written for a different size range. This one was intended for mid-range stones, hence the slightly complicated pavilion and crown. I like it in citrine, but can be cut in any material from quartz to rutile (RI = 1.54 - 2.62) with no changes. Suggested size = 8-12 mm
