Cardi B decided to commemorate the birth of her fourth child by casting a piece of her umbilical cord into gold chrome.

The rapper, 33, who recently had her son, her first baby with boyfriend Stefon Diggs, enlisted a company that specialises in such to create the special memento.

According to the company’s website, the keepsake is the baby’s “umbilical cord dehydrated in the shape of a heart and then dipped in gold chrome.”

Purchasing the stylized and preserved cord is $50, but the company also offers a $500 Placenta Encapsulation Service, which converts a woman’s placenta into pills. 

In a video shared by the company, someone can be seen forming Cardi’s keepsake. Another video shows that Cardi also opted for a placenta print, which is another service the company offers.
