The diamond necklace shown here isn’t just a heart, it’s a heart with a heart. The necklace is part of Petra’s Infinite Heart Collection from Fortunoff. Model and tsunami-survivor Petra Nemcova worked with the jewelry design team to create the collection. The Infinite Heart charm was inspired by the logo for Petra’s Happy Hearts Fund and is available in a bunch of styles ranging from a sterling silver piece that sells for $95 to the diamond and white gold necklace above which sells for $675. A portion of proceeds from each piece will benefit the charity, which provides aid to children who have suffered loss or hardship as a result of natural, economic or health related disasters. The collection will be available at Fortunoff starting February. Petra will also make an in-store appearance on February from 12-2 PM at Fortunoff’s Fifth Avenue store.
