This design was inspired by something from an episode of "Steven Universe". No joke. I basically took a symbol and adapted it into the crown. The deep pavilion and high dome should give this design the feel of a Portuguese cut rather than an SRB, and should only be used in lighter materials. The sequence is written for weight presevation. Works in materials from quartz to rutile (RI = 1.54 - 2.62) with no changes.
