Crafted in 18k Yellow Gold, this Black Diamond Baguette Heart Beat Necklace pairs our Fine Belcher Chain with the Baguette Black Diamond Heart Beat. Our versatile Heart Beats are a celebration of the things that make our hearts beat, translated into symbols, color, and light. Each one has a heart-shaped opening, a detail that feels like a secret just for you. Every time we choose to add a Heart Beat to a piece of jewelry, you make it more “you” and enrich your story in the most beautiful way.
