This gorgeous Black Opal chain is adorned with an opal gemstone that shimmers and plays with color, all set in an opulent gold vermeil chain. Rich golden vermeil contrasts nicely with the dark, enigmatic tones of black opal, with hints of red, blue, and green, to create a striking and sophisticated design. With the 2-inch extender that comes with the 16-inch chain, you may customize the fit to match any neckline.
