As of my last knowledge update in January 2022, there was no public information confirming that Jay-Z had presented Beyoncé with an island valued at $64,000,000 on their 10th wedding anniversary. It’s essential to be cautious about such claims and rumors, as they may not always be accurate or up-to-date.

Jay-Z and Beyoncé are a private couple, and while they have been known for their extravagant gifts and gestures to each other, details about their personal lives are often kept under wraps. It’s possible that new information has emerged since my last update, but I do not have access to real-time data to confirm such reports.

If this is indeed true, it would be a grand and luxurious gesture, but I recommend verifying the information from reliable sources or official statements to ensure its accuracy.
