JAY Z TRYING TO COP BLUE DIAMONDS FROM JACOB FOR HIS ANNIVERSARY!

Jay-Z was spotted shopping for some bling for wife Beyonce in honor of their fourth wedding anniversary, and sources told the Daily Mail that the diamonds he had his eyes on were, well, blue.

The rapper was snapped leaving Jacob & Co. jewelry store in Manhattan deep in conversation with pal and longtime associate Jacob Arabo Wednesday, but he appeared to leave empty-handed except for a water bottle.

According to the Mail, Jay-Z was interested in Arabo's collection of rare "Lumina" blue diamonds.

"I know he checked out colored diamonds, the rare blue 'Lumina' in particular," a source told the site.

Jay-Z and Beyonce have an affinity for the color; the rapper's album "The Blueprint 3" went platinum upon its release in 2009 and the diva singer frequently dons blue nail polish in honor of the couple's first child together, Blue Ivy, 3 months.

The jewelry shop stop comes amid rumors that the musical couple is set to renew their vows in a ceremony later this year.

A source tells Star magazine that Jay-Z "told Beyonce earlier this year that he wanted to marry her all over again."

"They want the ceremony to be simple but elegant," the magazine reports. "They're having Nobu cater it, and Jay put together a special presentation showing him and Bee through the years."

On Thursday, Beyonce let fans in on some personal moments of her life as well, with a newly launched Tumblr featuring photos of her and Jay-Z goofing off with family.

"This is my life, today, over the years - through my eyes," she wrote on the site. "My family, my travels, my love. This is where I share with you. This will continue to grow as I do."

The notoriously private star also wrote her very first tweet, garnering more than 3,500,000 followers in less than an hour.

"Hey World, It's B! I'm so excited to invite you to my new http://beyonce.com - we've been working hard, and it's finally ready for you XO," she wrote.

How much blue sh!t can we do?
