About this product

Badgley Mischka's certified lab grown heart-cut solitaire pendant necklace features a 3-carat diamond set in 14k gold with an 18-inch cable link chain and spring ring clasp. The diamond has a color grade of H-I and clarity of SI, and is chemically, physically, and optically identical to natural diamonds but grown in a controlled laboratory environment without mining. A Certificate of Assurance accompanies the piece, and rhodium plating enhances the white gold finish, which may wear over time and can be reapplied by a jeweler. This elegant necklace combines modern sustainability with timeless design.
