Oxytocin necklace 3D | sterling silver
One customer gave this 3D oxytocin necklace to their daughter when she graduated as a midwife. Oxytocin is part of labour and of breastfeeding, so it is a natural gift for the women who care for mothers and babies, from family, friends or colleagues.
Who It's For
- a daughter graduating as a midwife, or a daughter-in-law graduating from nursing
- a wife or partner who works in biochemistry
- a partner who is a therapist and explains oxytocin to her clients
- a medical student, from her partner
- a dear friend
- yourself, if obstetrics is your field
Christy s. bought one for herself: “The 3D oxytocin molecule is a beautiful and unique piece to represent the field of Obstetrics.” Veronica A. wears hers: “The solid silver gives this delicate looking necklace a satisfying heft.”
Oxytocin in Three Dimensions
Written out, oxytocin is nine amino acids. A disulfide bridge between its two cysteines closes the first six into a ring, and the last three trail off as a short tail. Its receptor, on cells in the uterus, the breast and elsewhere, recognises the hormone, and it needs magnesium to do it well. In a 1989 study of uterine oxytocin receptors, taking magnesium out of the solution lowered their affinity for oxytocin about 1,500-fold. A 2022 cryo-electron microscopy structure showed the magnesium ion sitting between the hormone and its receptor, held by both.

FAQ
How big is it, and how does it sit?
The pendant measures 48 mm (about 1.9 inches), a few millimetres short of two 2-euro coins side by side. It is a statement piece rather than a small charm. It hangs from both ends on a 45 cm (17.7 inch) sterling silver chain with a 5 cm (2 inch) extender and sits around the collarbone. Longer chains up to 80 cm can be added on this page. It is 925 sterling silver, nickel-free and hypoallergenic.
Is there a gold version, or a flat oxytocin necklace?
Yes. The 3D oxytocin necklace also comes in 18K gold vermeil at the same 48 mm. Choose the finish she already wears: the design is the same in both. The flat oxytocin necklace measures 62 mm and comes in sterling silver and gold vermeil. There is also an oxytocin ring in sterling silver.
Will it arrive in time, and what if it isn't right?
DHL Express delivers free in 1-5 business days worldwide, 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.
Does oxytocin have one fixed shape?
Not quite. In 1986 a team including the crystallographer Tom Blundell published X-ray structures of deamino-oxytocin, a close relative that lacks oxytocin's first amino group and works at least as well on the uterus. The resolution was better than 1.1 ångström. Each of the two crystal forms held two slightly different versions of the molecule, their disulfide bridges twisted in opposite directions. The authors suggested this flexibility may matter for how the hormone is recognised by its receptor and switches it on.
