Serotonin necklace H | 18K gold vermeil
One customer bought this serotonin necklace for a daughter studying psychology, ended up wearing it too, and had to order a second. In 18K gold vermeil, it's a gift for a woman who studies the mind, or for one who wears gold every day and likes a little chemistry with it.
Who It's For
- a daughter or granddaughter studying psychology or neuroscience
- a sister or friend studying pharmacy, chemistry or medicine
- a wife or partner, for her birthday or Christmas
- a best friend who loves chemistry as much as you do
- a pharmacist, psychologist or neuroscientist, as a necklace for work
- yourself, if gold is what you wear every day
Elena l. gave it to a younger sister studying pharmacy: “She loved the necklace since the first time she had it on her hands. Now, she wears it everyday. It's a cute way to say to someone that he/she makes you happy.” Ida S. bought one for herself: “It really is a very beautiful necklace, I've already received lots of compliments for it.”
How Serotonin Sends Its Signal
Serotonin doesn't carry a single message. What it does depends on the receptor it lands on, and the same molecule can excite one nerve cell and quieten the next. All but one of its receptor families pass the signal on through a chain of reactions inside the cell, which takes time. The exception is 5-HT3, which is itself a channel: when serotonin binds, it opens and lets charged particles straight into the cell, so it acts fast. Many 5-HT3 receptors sit on the nerves linking the gut to the brainstem. Chemotherapy can make the gut lining release a flood of serotonin, which triggers nausea and vomiting through them. That is why many anti-sickness medicines given with chemotherapy block this receptor.

FAQ
How big is the pendant, and how does it sit?
At 26 mm across (about 1 inch), the pendant is about the width of a 2-euro coin and a little wider than a US quarter. The chain attaches at both ends, so the pendant lies horizontally just below 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, are sold on this page. The finish is 2.5 microns of 18K gold over solid sterling silver.
Is there a silver version, or a vertical one?
Yes to both. The same horizontal pendant comes in sterling silver, also 26 mm. Choose the finish the recipient already wears. The vertical serotonin necklace (25 mm) hangs from a single point, so the molecule sits upright, and it also comes in both finishes. For matching earrings in gold vermeil there are serotonin studs (19 mm). The earring hoops, bracelet and ring come only in sterling silver.
Will it arrive in time, and what if it isn't right?
It ships free worldwide with DHL Express and arrives in 1-5 business days. We pay the import duties and taxes, so there is nothing to pay on delivery. It comes 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.
Who first named serotonin's receptors?
John Gaddum and Zuleika Picarelli, in 1957. Picarelli, a Brazilian pharmacologist, spent a year in Gaddum's pharmacology department in Edinburgh. They showed that serotonin makes guinea-pig gut contract in two separate ways. Morphine blocked one and dibenzyline the other, so they named them M and D receptors, M probably on the nerves and D on the muscle. The names were dropped, but both sites are still recognised among today's 5-HT3 and 5-HT2 receptors. Picarelli went on to chair biochemistry and pharmacology at the Escola Paulista de Medicina in São Paulo.
