The metal twists into the shape of two perfect hearts, each carefully holding a round stone. It resembles love and protection. Personalise the Heart Nest charm with a 3mm and a 2.5mm genuine or simulated birthstone to represent your loved ones, or pick Swarovski Zirconias of your preference. Choose from metal options of sterling silver or solid gold and add up to 2 engravings on the top. This charm fits all standard charm bracelets.
