The Crystal Heart Interchangeable Charm​ features an open design filled with faceted, violet tanzanite crystals. Violet symbolizes creativity and spirituality. Often associated with introspection, meditation and love, the color violet encourages us to tap into our intuition and embrace our heart's desires. Our new, interchangeable charm design lets you make the look all your own: swap out the charms or add symbols to make a charm necklace or bracelet that’s exactly your style.
