When “permanent” jewelry debuted a few years ago, “I didn’t foresee the trend would become a staple of a jewelry wardrobe in 2023, but it has,” one expert said.
On a recent summer afternoon, the Persée jewelry counter upstairs in the Galeries Lafayette Champs-Élysées was busy, with some shoppers inquiring about piercings, but most waiting to get the brand’s Eternam chain, delicate links of gold that are soldered on — forever.

“It’s like a jeweled tattoo,” said Nawal Laoui, the founder and owner of Persée, a Paris brand specializing in diamonds. “Customers like the idea of having a second-skin bracelet, which can be forgotten for its lightness, but remembered for its uniqueness. It’s a strong symbol of a bond that is welded to you, never to be removed again.”
The chains — available in 18-karat white, yellow or rose gold and with links that are 0.6 millimeter (0.02 inch), 0.8 millimeter and 1.0 millimeter wide — actually could be cut off with pliers, if necessary. But Ms. Laoui, who flies often, stressed that her Eternam bracelets and rings have never caused a problem at airport security. (They likely would have to be removed, however, for an MRI or surgery.)
Such “eternal” jewelry has grown in popularity over the last few years, said JB Jones, co-founder of NYC Jewelry Week.
