Enneper's surface, with 3 lobes. This is a minimal surface, like a soap bubble. (Imagine that the perimeter is formed of wire, then dip it into a soap solution.) It has a very sensual and organic shape, and is particularly beautiful in silver and gold plated brass. The equation is trigonometric, plotted in Mathematica, thickened in Blender. No findings or chain are included.This model is slightly thicker than my Enneper Silver Earring model, allowing casting in the gold and rhodium plated brass materials.
