Jewellery care +

More care tipsThe measurements of each piece are shown in centimetres on its product page.
| Length | Style |
|---|---|
| 35–38 cm | Choker — close to the neck |
| 40–45 cm | Classic — at the base of the neck |
| 50–55 cm | Mid — below the collarbone |
| 60 cm + | Long — sautoir style |
Most of our necklaces sit in the classic range and many are extendable (for example, from 40 to 45 cm).
Tip: measure a necklace you already wear, or use a piece of string and a ruler.
Measure your wrist with a tape measure (or a piece of string you then measure) and add 1–1.5 cm of ease. Many of our bracelets are adjustable.

Measure the inner diameter of a ring you already wear and compare it with the chart — or wrap a thread around your finger and divide the length by 3.14.

From the founder
"I created Le Marshand with the idea that jewellery should be part of your everyday - not something worn only on special occasions. Jewellery should reflect who you are, how you feel and the story you're writing each day."
