water - H2O necklace | sterling silver
H2O may be the best-known formula there is, and most of what goes on inside a living cell takes place in water. This water necklace is a quiet present for a friend in science, and a simple pendant she can wear every day.
Who It's For
- a friend finishing her PhD, as a keepsake of her project
- a friend who works in chemistry or biochemistry
- a friend who lives for the sea or the pool
- yourself, if you love art and science in equal measure
And for yourself, if water is part of your own story.
Sheila M. gave it to a friend for her PhD: “She now has a great reminder of her PhD project that she can wear whenever she wants.”
Water Is Never Still
Water looks calm, but its molecules never settle. Each links to as many as four neighbours through hydrogen bonds, and a typical bond lasts about a picosecond, a trillionth of a second, before it breaks and forms again, often with a different neighbour. They also trade hydrogens: at any moment in pure water at 25 °C, about two molecules in every billion have handed a hydrogen ion to a neighbour, which gives a pH of 7. A hydrogen ion barely travels as itself. It is passed along the bonds from molecule to molecule, an idea first sketched by Theodor von Grotthuss in 1806. That relay is why hydrogen ions move through water several times faster than sodium or potassium ions.

FAQ
How big is the pendant, and how does it sit?
The pendant measures 15 mm (about 0.6 inch), a little smaller than a 1-cent euro coin and smaller than a US dime. It hangs from a small loop on a 45 cm (17.7 inch) sterling silver chain with a 5 cm (2 inch) extender, and sits below the collarbone. Extra chains of 40, 42, 45 and 50 cm (each with the extender) or 80 cm can be added on this page. Our sterling silver is nickel-free and hypoallergenic. Store it dry and wipe it with a soft cloth.
Is there a gold version?
Yes. The same 15 mm water pendant comes in gold vermeil, 2.5 microns of 18K gold over solid sterling silver, on a 45 cm gold vermeil chain with a 5 cm extender. Choose the finish she already wears. The design is the same in both finishes.
Will it arrive in time, and what if it isn't right?
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.
Is there such a thing as heavy water?
Yes. About one hydrogen atom in 6,400 is deuterium, hydrogen with an extra neutron and about twice the mass. Harold Urey found it at Columbia in 1931 with George Murphy, in hydrogen that Ferdinand Brickwedde had concentrated in Washington by evaporating liquid hydrogen. Urey received the 1934 Nobel Prize in Chemistry “for his discovery of heavy hydrogen”. Gilbert N. Lewis made pure heavy water in 1933. It is about 11 per cent denser than ordinary water, so a heavy-water ice cube sinks in a glass of tap water.
