TwentyFour’s Digital-Age Locket Is a Virtual Vault
The “Vault” charm, our Piece of the Week, expands on the memories that can be stored in a locket by connecting to your phone.
New York City-based fine jewelry studio TwentyFour has taken the design of a locket and reimagined it for the digital age.
On April 24, we’re featuring TwentyFour’s “Vault” charm as our Piece of the Week. While it appears to be a gold charm, the locket holds multiple mediums.
“Vault began with a question about the relevance of the traditional locket. Historically, lockets hold a photograph, but the way we capture and store memories today has completely changed,” said Lee Bridge, founder and designer of TwentyFour.
“I wanted to create a piece that could hold more than one moment. Something that could carry a voice, a video, a song … a full story.”
The front of the 18-karat yellow gold charm features 0.85 carats of French pavé diamonds set in platinum, while the reverse reveals a black circle, which is the NFC device that holds the locket’s data.
NFC, short for near-field communication, is technology that exchanges data between devices, similar to Bluetooth and RFID but with better security, according to Digital Trends.
It is the same technology that powers mobile payments like Apple Pay and Google Pay.
NFC works with iPhone 7 or newer and Android devices; however, tablets and computers do not support the technology yet.
When tapped on the back of a smartphone, the “Vault” is unlocked, and the phone opens to the wearer’s private, personalized page on the TwentyFour website.
The page can have up to five images, a short video, a voice note, a handwriting sample, and as many as three links to songs or playlists from Spotify, Apple Music, or YouTube.
A sample page can be seen here.
TwentyFour said it has plans to launch a dedicated app with more advanced customization and functionality, projected to roll out in 2027.
After the charm has been purchased, Twenty Four’s “digital concierge” helps curate the memories that will populate the wearer’s page.
“I did not want to make tech jewelry. I wanted to expand how jewelry holds memory,” Bridge said.
“Jewelry has always been symbolic, tied to a person or a moment. I wanted to make that tangible. The technology is fully embedded, so the piece remains visually traditional, but what it carries is far more layered.”

The “Vault” collection, which debuted in August 2025, also includes the “Major Vault” charm with a 3.06-carat pear-cut diamond and the “Micro Vault” charm accented by a 0.10-carat star-set diamond, which launched in February.

The collection offers multiple customization options and Bridge added that there are plans to expand it to include more gemstone-focused designs.
All three Vault charms are available in 14-karat or 18-karat yellow or white gold with lab-grown or natural diamonds.
The standard Vault charm also is offered in two-tone 18-karat yellow gold and platinum.
The two-tone Vault charm with natural diamonds retails for $4,675 alone and $5,225 when sold with the brand’s “Cable Chain No. 2,” which is featured in the image at the top of the article.
It is available on the TwentyFour website.
