Hermes Farandole Long Necklace 120 Sterling Silver H104568B 00

One hundred and twenty centimetres is the length that turns a necklace into a tool. Let the Farandole 120 hang straight and it reaches the waist, with an anchor link resting at intervals the whole way down; loop it twice and it becomes a double strand sitting comfortably on the chest. Both are correct, and I switch between them depending on the neckline.

In sterling silver the chain stays cool and, after a few months, develops a soft grey bloom that makes it look older and better than new. The links here are Chaine d’Ancre at a medium scale, so they catch light without looking busy.

My usual version is doubled, over a fine black turtleneck, with one length left slightly longer than the other so it does not look measured. Over a striped shirt, worn long, it does the work a scarf would do, without the heat.

Two trade-offs. This length is a commitment to layering: on a plain t-shirt it can look like a lot of chain with nothing to do. And silver demands attention in humid weather, so a polishing cloth lives next to where I keep it. Made in France, 925/1000.

The honest trade-off is that a chain this long is always doing something: doubled, knotted, or wrapped a third time, and if you prefer jewellery that hangs still, it will feel busy. When it is right, nothing else in a wardrobe does the same work. Mine lives doubled over a plain knit and takes ten seconds to arrange.
