Luk Cox Idoya Lahortiga, AKA Somersault 18:24, are jewelers who makes 3D printed science objects in gold, brass and silver, like the Darwinian phylogenetic tree necklace pictured above, and invests the profits in freely usable and shareable science education resources.
A quick rummage through their store yields many more treasures: mitochondria necklaces, the Fibonacci necklace, plasma membranes and much more. (via Geeky Merch)
