Summary

This is a Star Sapphire ring, the violet in the Emotional Rainbow that includes Green Lanterns. It can be printed using dual-extrusion, preferably with pink or violet filament for the body and white filament for the top. The ring is printed symbol-down, and the circular shape presents a nice first layer -- no raft should be needed. If you print directly on glass, the surface should come out nice and smooth.
