Casper Smart’s Expensive Birthday Gift for Jennifer Lopez [PHOTO]

Jennifer Lopez reportedly received expensive jewlery from her boyfriend, Casper Smart, for her recent 44th birthday.

Smart knew better to buy the pop singer any jewelry. Instead, he hunted one-of-a-kind vintage pieces from the Platt Boutique in L.A.

Smart  selected  a '70s yellow gold and diamond chain link bracelet and a '40s gold and diamond ring, both with a coordinating buckle motif.

Mariel and Rob, longtime stylists of Lopez, helped Smart to buy the perfect gift for J. Lo. They said that Platt Boutique is the place to buy a unique gift.

 "He told me he had bought her jewelry before, but never vintage," owner Larry Platt told PEOPLE, "so he wanted to go in a different direction, something one-of-a-kind."

Platt described Smart as having a good eye for what Lopez would have wanted.

"He was looking for vintage pieces that had a chic, modern feel to them. He told me that there are only two pieces of jewelry that Jennifer wears on a daily basis, so he wanted to pick pieces that he felt she would wear all the time and could go with everything," Platt said.

Lopez appeared to be wearing the bracelet out on a walk with Smart a few days ago.

"He appreciated the fact that pieces were beautifully made, from a different era and were completely unique," Platt said.
