These matching serotonin and dopamine earrings bring the happiess molecules to your ears!   They are set up just like my standard molecule pendants except a fraction of the size, with handmade glass jumper rings connecting them to stainless steel earring hoops.   This is the first pair of this design to be released to the public, and several experimental ones have been rigorously tested for durability and comfort with all positive feedback!   The small discs are fully sealed so no dust or moisture will ever get trapped inside, and each molecule glows bright green under UV lighting.
