TwentyFour’s Vault charm turns a locket into a digital keepsake

The locket has always been a vessel for what cannot be said aloud. TwentyFour’s Vault charm keeps that private promise intact, then gives it a phone-era upgrade: tap the gold charm to a handset and it opens a private page on the brand’s site, where photos, voice notes, playlists, handwriting and short videos can live behind one piece of jewelry. Priced at $2,150, the charm is also offered as a $2,650 Vault necklace, an $850 Micro Vault charm and a $3,600 Major Vault charm.

Founder Lee Bridge built the idea around expansion, not replacement. Rather than reducing a locket to a single photograph, Vault is meant to hold more than one memory, so a child’s voice, a favorite song and a handwritten note can sit in the same hidden archive. TwentyFour says buyers are paired with a personal concierge to help curate the Vault, which pushes the piece closer to a custom keepsake than a novelty gadget.

That emotional logic has deep roots. Locket historian and acquisitions expert Cristina Mattern has said lockets have been popular for more than five centuries, historically tied to mourning and romance before photographs became the standard miniature relic inside them. She also pointed to earlier sentimental forms such as Stuart-crystal slides and Victorian lockets, a reminder that TwentyFour is not inventing the idea from scratch so much as translating it for a world that stores memory on a screen.

The harder question is whether NFC adds intimacy or just a clever trick. In the best case, it gives the wearer a secret only a trusted phone tap can unlock, which feels true to the spirit of a locket. It also raises the practical concerns meaningful-jewelry buyers care about most: how long the digital page will remain accessible, whether the experience stays easy over time, and whether the memory feels as durable as a locket that needs no software update to work.

TwentyFour’s own positioning helps the piece land in luxury, not tech. The New York City studio, founded in 2020, says it is built on the idea that jewelry should mean something. Its five-person team is mostly women, and the brand works in solid 14k, 18k and platinum, with more than 40 metal color options and lab-grown diamonds. It also says it uses recycled gold, prioritizes fair-trade, positive-impact sourcing and works with small family-owned mines and gemstone cutters in the U.S., Mexico, Africa, India and Brazil.

Seen against smart-jewelry precedent, Vault arrives in a category that is still defining itself. Galatea’s Momento collection has claimed NFC-enabled fine jewelry for messages and media, while other NFC pieces use hidden chips to open apps and store memories. TwentyFour’s version feels more restrained and more romantic, which is exactly why it works: the technology matters only if it deepens the keep-sake into something a traditional heirloom could not hold.
