The mathematics of stereographic projection retrieves this banded torus from the unit sphere in four-space. The bands' edges are unit circles, any two linked. The torus itself is gently tilted in four-space, giving its solid shadow in three-space an enticing asymmetry. More about the math behind Luna is explained in a shop blog post.
This eye-catching 1 inch (25mm) pendant is 3D printed in rhodium-plated brass, polished to a chrome-like luster on its outer surface, and paired with an 18-inch sterling silver French rope chain with lobster-claw clasp. A black velvet storage bag is included.
