A nice little precious pendant and a fascinating shape,about 2cm wide, available in various precious or plated metals.
That is what happens when you cut a torus with a Mobius ribbon (and then manage to get round edges...)
It is intended as Infinity in a nutshell, with a twist and a swirl to make it more inuitive.
The current dimensions are optimised for precious metals, but I can make a model the size you want, even with other materials, as long as it fits Shapeways' guidelines for the material you desire.
