Möbius strip necklace | 18K gold vermeil
Mathematicians reach for the Möbius strip when they want to show how strange a simple loop can be. This gold vermeil Möbius strip necklace is for the partner who lights up at a good puzzle, or for yourself, as a piece that starts conversations.
Who It's For
- a partner who loves mathematics, as a surprise for no particular reason
- a daughter graduating in mathematics, physics or computer science
- a friend turning 40, or any birthday that deserves more than flowers
- a teacher who made topology click, or a colleague leaving the department
- yourself, if you already wear gold and want a piece with a story behind it
From a review of the silver version, nonsensicali: “Very well received 40th birthday gift”. Patrik H. on the gold version: “Looks good and arrived quickly.”
The Mathematics of Twisted Bands
A paper band with no twist has two sides and two edges. Give it one half twist before joining the ends and it has one side and one edge, and that single edge runs twice around the strip before it meets itself. Add a second half twist and the band has two sides again. The rule holds for any number: an odd number of half twists gives one side, an even number gives two. Engineers have put the single side to work. Several patents cover conveyor belts with a half twist, so that the whole surface wears evenly instead of only one face. In 1923 Lee De Forest patented a Möbius filmstrip that records sound on both faces.

FAQ
How big is it, and how does it hang?
It is a bold piece: the pendant measures 29 mm across (about 1.1 inches), wider than a 2-euro coin. The chain runs through the loop itself. It comes on a 45 cm (17.7 inch) gold vermeil chain with a 5 cm (2 inch) extender and sits around the collarbone or just below. It is 18K gold vermeil, 2.5 microns of 18K gold over solid sterling silver, nickel-free and hypoallergenic. Take it off for swimming and the gym, and a soft cloth keeps the gold bright.
Is there a silver version, or a different chain length?
Yes. The same Möbius strip necklace comes in sterling silver. Choose the finish she already wears: the design and size are the same in both. For another length, an extra chain in gold vermeil or sterling silver is offered on this page in 40, 42, 45 or 50 cm, each with the 5 cm extender, or 80 cm without one.
Is delivery free, and what if it isn't right?
Yes. 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.
Is the recycling symbol a Möbius strip?
Yes, in its original design. In 1970, the year of the first Earth Day, the Container Corporation of America, a paperboard maker, ran a student contest for a recycling symbol. Gary Anderson, a University of Southern California student fresh from its architecture programme, won it with three chasing arrows folded into a Möbius strip. The judges met at the International Design Conference in Aspen, and his prize was a $2,500 scholarship. Anderson saw the strip as “a finite object, but its one surface is infinite in a way.”
