Mark Zuckerberg finally spilled the beans about his new chain-necklace look

• Mark Zuckerberg revealed the reason for his new chain necklace.
• The Meta exec said he's designing his own piece of jewelry with a heartfelt message.

The hype around Mark Zuckerberg's new chain lives on, and the story behind it is pretty endearing.

The Meta CEO spoke with Eva Chen, the head of Instagram's fashion partnerships, about developments for its Ray-Ban smart glasses and spilled more information on his viral accessory choices.

"I'm in the process of designing a long-term chain," he said Tuesday in an Instagram post.

As part of his "design process," he said he's testing out necklaces that would eventually hold an engraving of the prayer he reads to his daughters.

Zuckerberg was spotted wearing a shorter-looking chain last week, prompting memes and talk of a "glow-up." (Another popular image floating around was of the billionaire edited to look like he had a beard, but the chain is definitely real.)

This new venture into fashion has drawn comparisons to "mob chic" trends and rapper swag. But Zuckerberg said the necklace boiled down to a sentimental gesture to his children.

Either way, the move has certainly earned the Meta chief some internet cool points — though perhaps not from Instagram's Chen, who suggested the chain he was wearing in Tuesday's video should be a bit shorter.
