The store, which launches today (1 November), offers Merci Maman’s necklaces and bracelets, which can be hand-engraved on site, seven days a week.
The brand has experienced “rapid growth” over the past two years, with sales increasing by nearly 70%.
In addition to in-store, Merci Maman is set to launch online on the Selfridges website, just in time for the busy festive period.
Clemmie Reed, platforms manager, said: “I am so excited to see Merci Maman open a concession in Selfridges.
“I can’t think of a more perfect location for our first long-term retail presence than this iconic London department store. We will be hand-engraving in-store until Christmas and beyond!”
Alix Stanworth, director of sales and marketing, added: “It’s a momentous occasion for Merci Maman to launch in such a renowned department store.
“We look forward to bringing our unique personalisation concept in-store with our talented team of artists. This is months of hard work that has come to fruition.”
