Decoage

18KT White Gold Black Onyx and Diamond Heart Necklace 18in

$1,300.00

A heart of contrasts - the Decoage Black Onyx and Diamond Heart Necklace in 18KT white gold pairs the deep, opaque mystery of natural black onyx with brilliant white diamonds in a heart silhouette. The graphic contrast between the black center and sparkling diamond frame creates a pendant that is simultaneously romantic and bold - a striking twist on the classic diamond heart necklace for those who prefer their romance with an edge.
