This necklace set pairs a bezel-set lab grown diamond pendant with a wheat chain necklace and a box chain necklace for a bold, layered look.

  • 0.10 ct. tw. emerald-cut lab grown diamond — features a bezel setting on the pendant.
  • Cable chain — the diamond pendant hangs from it, fastening with a lobster clasp and adjustable to either 16 or 18 inches to suit individual preference.
  • Hollow wheat and box chains — each measure 18 inches long, completing the set for a textural, layered look.
  • Lobster clasp — fastens each of the three necklaces in the set securely at the back of the neckline.
  • 1/6 inch pendant width — keeps the diamond solitaire sleek within the layered stack.
  • Mixed-necklace set — combines a diamond pendant with metal chains for a versatile, everyday layering appeal.
