This serotonin charm features a constellation-inspired molecular drawing with small sparkly details to create an elegant necklace for science lovers and fans of the notorious neurotransmitter. 

The gems on the necklace depict oxygen and nitrogen atoms and carbon atoms are depicted by little stars. While hydrogen atoms are omitted in this design (as they often are in simple organic chemistry drawings), the nod to stars are a way of acknowledging hydrogen - as these gaseous celestial bodies primarily contain hydrogen and helium.
