I love Portuguese-style cuts, but I wanted to see if I could use radial symmetry to get more of a whirlpool effect. It turns out that not only does this design swirl, but it also has different radial zones that you'd expect to see in a real whirlpool! The reflection pattern is awesome. Designed for blue CZ, and only really works in CZ. Suggested size = 10-20 mm
