• Someone paid $40,500 for a necklace that Mark Zuckerberg may have only worn once. Its retail value is only $425. But they also get a video from Zuckerberg himself. 

You may have noticed a difference in Meta CEO Mark Zuckerberg’s style lately. He rocks longer, curlier, messier hair, and silver or gold chains. It feels like a sea change for Zuckerberg, who, for many years after he founded Facebook, was usually seen in only plain gray T-shirts or hoodies.
