1ct, 1.5ct, 2ct Lab-Grown Diamond 4-Prong Pendant Necklace

A lab-grown diamond solitaire necklace designed for a sleek, radiant look. By eliminating jump rings and attaching the chain directly to the four-prong setting, the piece maintains a light and refined appearance even from the side profile.

Available in three sizes—1ct, 1.5ct, and 2ct—each diamond is D-color, VVS2, and 3EX (H&C). All sizes come with an IGI certification.
