A nod to the idea of Ombré here.
Ombré
Description
Ombré is the gradual blending of one color hue to another, usually moving tints and shades from light to dark.

I show this strand with a black leather double-strand cuff.
Like Vera Wang, I never met a basic black I did like…. this strand gets lots of action as a stand out against basic black.
