This 18K yellow gold Yvonne Léon heart tourmaline necklace is crafted in France from a chain of mixed links forming contrasting halves. It's accented with a heart-shaped pink tourmaline at the centre and fastens with a spring clasp. A stone that opens the heart chakra, tourmaline is said to reduce stress and kindle positive emotions. Safe to say, nothing boosts our mood like a new Yvonne Léon necklace.
