Serotonin and Dopamine
MOLECULAR JEWELRY

Start a conversation with this clever jewelry fashioned from the shapes of a few rather important molecules. Serotonin, a chemical responsible for happiness and relaxation, has an elegant shape that makes for a terrific necklace that will make you grin as much as the chemical it represents. And the dopamine earrings represent passion and pleasure with splendid scientific flair. Each piece is sterling silver and comes in a recycled box with an informational tag. Handmade in California by Dr. Raven Hanna.
