This pendant started out just like my others; a hollowed out torus("donut") with some squiggly pattern on the outside.
Cut it in half and added a ring on the back since my girlfriend thought that made more sense with this particular design.
The ring/hole at the back is approx. 3x4mm so a normal necklace chain should go through but it can just as easily be mounted with a earring hook.
