About this product

The Badgley Mischka lab grown diamond tennis necklace features 28.5 total carats of round-cut diamonds set in either 14k white gold or 14k yellow gold, with an approximate length of 18 inches and a box lock clasp. The diamonds have a color rating of I-J and clarity of VS2, and the piece is crafted using lab-grown gemstones that are chemically, physically, and optically identical to natural diamonds. A rhodium plating enhances the shine of the white gold version, which may wear off over time and can be reapplied by a jeweler. The necklace requires special care due to its gemstone composition.

  • 28.5 total carat weight
  • round-cut lab grown diamonds
  • 14k white or yellow gold setting
  • 18" length with box clasp
  • rhodium-plated white gold option
  • VS2 clarity, I-J color grade
