Dopamine is a natural stimulant that produces ecstasy, focused attention, motivation, and goal oriented behavior. It’s associated with arousal and, at very high levels, anxiety and fear. Dopamine is the driving force behind the excitement and anticipation that are a part of love. This dopamine necklace is a great way to express love to that special someone! This chemical structure pendant is fabricated in Polly's studio in Portland, Oregon and affixed to a 16 inch chain (adjustable to 17 inches). The name of each chemical is stamped into a tiny tag that hangs down the back of the necklace, and all findings are securely soldered. Each piece is then finished with a hand-rubbed, oxidized patina and arrives gift boxed on a handcrafted display card containing information about the chemical structure.
