This heart pendant necklace in 14 karat yellow gold features a striking half-and-half design. One side of the heart is pavé-set with seventy (70) round brilliant cut diamonds totaling .55 carats, while the other half showcases sleek black onyx for contrast. The diamonds carry a near colorless G-H color grade and SI1 clarity, meaning they face up white and bright with no visible inclusions to the naked eye.

A single bezel-set diamond sits on the 17-18 inch chain, adding a subtle accent. The piece secures with a lobster clasp and sits beautifully at the collarbone. The contrasting materials create a bold, graphic look that works as well with casual pieces as it does dressed up.
