Solid Sterling Minimalist Black Onyx Ring created by Wildflowyr Jewelry I created this solid sterling silver black onyx ring from patterned floral wire. It's 3.4mm in width and very sturdy. Inside the 6mm gallery bezel, I inserted a genuine black onyx cabochon. Please choose your size and your metal finish: either shiny sterling silver or the antiqued/darkened sterling silver (shown). Gift boxed with cute bow. I offer free resizing on all purchases. If you need a free disposable ring sizer, please ask.
