Description

 

Black Onyx Tennis Necklace in 14k Rose Gold

A continuous line of prong-set square black onyx stones runs the full 18-inch length in 14k rose gold, creating a bold, uninterrupted band of deep black and warm blush metal. The sharp geometry of the square cuts gives this tennis necklace an edge that round stone versions lack. Secured with a polished box clasp. Designed for both men and women, it wears equally well against bare skin, a white shirt, or layered with other chains. Dark, refined, and quietly powerful.

It’s fabulous that the pieces are inspired by brilliant people. I love to wear my Le Soleil Choker for an exotic and sexy touch.
