Solid Sterling Tiny Minimalist Black Onyx Ring created by Wildflowyr Jewelry I created this solid sterling silver black onyx ring from patterned full moon floral wire. It's 2.7mm in width and very sturdy. Inside the little 4mm serrated 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.
