This 18 karat white gold pendant necklace features a .40 carat round brilliant cut diamond with SI2 clarity and I color grade. The diamond appears to float on the chain, creating movement and light reflection as you wear it. At 15-16 inches in length, the necklace sits at a flattering position on the neck. This piece works well on its own for everyday wear or layered with other necklaces for a more dramatic look.
