Dopamine serotonin necklace H | 18K gold vermeil
If gold is what she wears every day, this dopamine serotonin necklace is the one to give her: two of the brain's chemical messengers, linked in 18K gold vermeil. One career scientist who wears it says it draws compliments every time.
Who It's For
- a daughter graduating in biochemistry, for Christmas or the day itself
- a girlfriend or partner, for her birthday or for no reason at all
- a sister studying pharmacy or medicine, once her exams are behind her
- a friend who reads everything about the brain, as a thank-you
- a colleague in psychiatry or neuroscience, when she retires or moves on
- yourself, if you have wanted this pair in gold for a while, or if these two molecules are part of your own story
Ludwig G. bought the silver version as a gift: “It made for a lovely present for my partner. She especially loved the design.” Emma D. bought this gold one for herself: “I have had my eye on this necklace ever since it came out in silver about 4 years back. Was always sad that it didn’t come in gold and checked the website every few months so I was super excited when I saw the gold version.”
Where the Brain Makes Dopamine and Serotonin
Most of the brain's dopamine comes from neurons in two small areas of the midbrain. One is the substantia nigra, Latin for “black substance”. It looks dark because its neurons slowly fill with neuromelanin, a pigment that forms as dopamine oxidises. The pigment builds up over a lifetime, so the area darkens with age. Serotonin neurons gather in the raphe nuclei, named from the Greek for “seam” because they run along the midline of the brainstem. In animal studies they fire steadily while awake, slow down in deep sleep and fall almost silent in REM sleep, the stage of most vivid dreams.

FAQ
How big is it, how does it sit, and what is it made of?
The pendant is 40 mm wide (about 1.6 inches), roughly one and a half times a 2-euro coin. The chain attaches at both ends, so it sits around the collarbone, on a 45 cm (17.7 inch) gold vermeil chain with a 5 cm (2 inch) extender. Extra chains of 40, 42, 45 or 50 cm with extender, or 80 cm, can be added on this page in gold vermeil or silver. It is 2.5 microns of 18K gold over sterling silver, nickel-free. Take it off to swim or shower.
Gold, silver or two-tone, horizontal or vertical?
Every version is 40 mm. This horizontal one hangs from both ends and also comes in sterling silver, or two-tone with dopamine in gold vermeil and serotonin in silver. The vertical version hangs from a single point for a longer, narrower line, in gold vermeil or silver. Choose the finish she already wears. Whichever you pick, it is the same pair, dopamine and serotonin. The metal and the hang are what differ.
How fast does it arrive, and can it be returned?
DHL Express delivers it free worldwide in 1-5 business days, and we pay the import duties and taxes, so nothing is due at the door. It arrives in a ready-to-gift jewelry box and festive envelope. If it isn't right, our 30-day “Love It or Return It” policy applies.
What makes dopamine neurons fire?
Surprise, more than pleasure. In the 1980s and 1990s, Wolfram Schultz at the University of Fribourg recorded single dopamine neurons in monkeys. An unexpected sip of juice made them fire. Once a light or tone came to announce the juice, they fired at the signal instead and barely reacted to the juice. When the juice failed to arrive, they went quiet at the moment it was due. In 1997, Schultz, Peter Dayan and Read Montague argued that this matches the reward prediction error, a teaching signal from machine-learning theory.
