Ordinary half-heart necklaces are boring. You get a half, and it will fit with any other half of the same mass-produced necklace! What if you don't even want a heart, but something a little more unique?
Enter the Combination Medallion necklace. Every set is uniquely generated by a Blender script -- there are over a half-million possible necklaces! Add your initials, and you get a 100% unique necklace that will only mesh with one half.
A heart-shaped version is also available here: www.shapeways.com/model/204105/combination_heart.html
Necklace cord not included.
Thanks to José I. Romero for an insane amount of work on this design.
