For all you non-scientists out there, Theobromine is a mild stimulant related to caffeine that makes up about 2% of cacao beans.  Scientist turned jeweler, Raven Hanna, and her Made With Molecules jewelry line specializes in accessories in the shape of molecules.  Melding science and eco art, she made this necklace (above) using reclaimed silver.

Theobromine is thought to elevate one’s mood by causing the release of feel-good neurotransmitters like serotonin and dopamine – perhaps wearing this necklace can have the same effect.  More molecular minutiae – the name theobromine is derived from Greek words, meaning “food of the gods.”  For the health benefits from the flavonoids and antioxidants in chocolate, choose the darkest varieties.

From Raven’s series of silver molecule jewelry is another personal fave, the Dopemine Keychain (below):
