First-ever Ivy Heart Design in 3D -- It's an original design from our studio in Boston, MA. This design resembles an ivy leaf, which is the first subject referred to as “heart shape” centuries ago. This ancient heart shape is reproduced in a geometric 3d structure to create a modern and dainty look, making it great for day-to-day wear and special occasions. Engraved words “I Love You to The Moon and Back” reveal the meaning of Ivy Heart – love grows like ivy! 925 Sterling Silver Necklace with Austrian Crystals -- The Ivy Heart is supported by a genuine stamped 925 sterling silver chain that is 18-inches long with a 2-inch extender. It finishes with a lobster claw clasp. At the heart of this necklace rests an 0.88 x 0.88-inch birthstone made with the most prestigious category of fine cut crystals- Austrian crystals. For further durability the entire piece is plated with extra thick 18K rose gold and a protective layer on top to prevent tarnishing.

Whether it’s to celebrate a birthday, or you are just looking to add a pop of color to your outfits, this is a personalized keepsake you or your loved ones will cherish for years to come.
